This, of course, requires you to be completely open and honest about your desires and that they're not jerks.

They already think you're a superstar, so it really won't be that much of a surprise when you say something like, "I had so much fun 'liberating our data' that I'd like to start my own service business doing the same thing for others."

Smart business people like helping others, especially helping others get started. They seem so sense that the karma will eventually come back to them (and I believe they're right). They also understand (even better than you) the business benefits of your work and can really help you focus your new business.

Ask them (starting with the top person, of course) for guidance on how to get started. You may be surprised how much you learn from them and how willing they are to help. You may think you know how much your work has helped them, but I bet they have more to share that you don't already know.

They probably can be the source for great leads, their vendors, their customers, other companies in the boss's CEO or Tech circle, golf buddies, who knows. For example, if your owner/president/CEO has an associate who would benefit from your services, everyone wins when he recommends you.

As long as they don't feel their core business threatened by your service business (helping their competitors), your own employer may be the best source for ideas and leads to starting your own service business. Give it a shot.

Rarely will you get a broad enough mandate to actually pull it off (based on your description). The other problem is entirely custom solutions put companies off because they then have to rely on your for support (one lucrative area that I do consultancy is supporting such programs for companies silly enough to go that route :) costs 'em a fortune). A custom solution sounds expensive from a companies perspective; both in cost but also in development time.

But most importantly the concept of "data liberation" and custom built databases are just not really on the commercial radar at the moment. Selling it to them could be pretty time consuming. To give you an example Im currently working with a company that are doing some pretty cool things - they've asked me to work on expanding their web app and database. It's a total mess and I have suggested a complete redesign which will cost about the same and be a lot easier for the both of us; they are resisting like hell...

(this is purely my opinion ofc, YMMV)

Not to put you off; but it is worth considering it from this perspective now rather than later. To answer your questions:

Where should I look for my first client?

People you know. I started contracting through a friend who, via religious connections, had a lot of eager clients/friends with work. However based on your description this is probably a very hard market to sell to.

Would I have to link up with an existing consulting firm or can individuals find success in this space?

Depends how much success you want - but I would say no. The resources and tools (legal templates, time tracking, invoicing) are now freely available on the web with a little looking. The only real need you may have is getting a foot in the door with large corps (which strike me as your target market).

Is this even a problem that businesses acknowledge?

See above. I suspect you will have to work pretty hard to sell this as a concept - at least initially.

My main thought is that rarely can a company pull either their business or tech people off of "working in" the company to "work on" the company for a few weeks to improve their reporting.

I actually have an anecdote about reporting in a piece of software we use. It's a highly customized database which then lets you design reports using Microsoft Report Server. Honestly, it's, really, a complete nightmare to use. But is it cost effective to get a consultant in to make it like, say, Gmail? That would be a dream (and if I had the decision you'd be at work on it tomorrow morning :)) but the truth is that your additions would mean re-auditing the whole thing, hiring other consultants to ensure it met data standards, retrain staff, etc.

Essentially what I am saying is that while the trade off of your cost vs. the man-hours saved is probably a net gain. When you get into a largish company lots of additional costs come into effect.

In addition (and this is probably a more important factor) habit breeds contempt; or, rather, if I was using this DB for the first time today I would hate it. But after 2 years it doesn't bother me any more.

If you came to us with a knowledge of the software, our requirements and a proposal of how to beat it then that would probably be considered - making a pitch like that can be hard though (because how do you know what we use and how). Something with before/after figures dressed up in the kind of language managers like.

Turning up with a "vague" (If you follow me) proposal to liberate databases is nice, but unlikely to hook anyone in the few minutes pitch window.

Again; not to put you off. But you may well need to use a different approach to "normal" consultants to get companies involved (I really wanted to give you a suggestion here but I am struggling, sorry).

My experience is that a company would rather assemble a team of low level business people to power through raw data or cobbled together observations for weeks rather than pull a developer off of doing CSS tweaks on the company's about page to actually solve the problem once in for all.

Using good tools can be a religious experience and make a company much leaner, meaner, and effective. However building good tools is high risk and rarely something company's want to work on (hence the problem with enterprise software in general).

You need to market your services to high level decision makers and be adroit at negotiating the murky waters you'll be in (essentially competing with or doing the work of an existing team).

Your experience is in a young startup which hasn't accumulated layers of legacy cruft, with a reasonable schema, where you understand the data model, and you have good relations with key players you need to cooperate with. As a result you encountered none of the common problems that are endemic in more established companies.

I say this as warning, not discouragement. As you pursue this course, be warned that you will encounter those problems and they will take more time than you think. Be prepared for that, don't over promise, and when you arrive at a company pay attention to those possible roadblocks so that they don't catch you by surprise. Because forewarned is fore armed.

If I was making a change in this direction, here is what I would look for:

1 - contract job listings or small consulting firms that do data warehousing, ETL dev, and reporting. 2 - Mid-size companies in a specific industry that need this type of custom reporting. Financial services companies are immediate targets.

One caveat - my personal search has indicated that many companies are tightly (very tightly) bound to using a report solution from a big vendor (Sas, Cognos, MS, or Microstrateg) and will probably NOT deviate from that platform. These types of places view reports using a specific provider as a very good thing seeing how they can hire report devs with that exact skillset when they need new reports or additional data sources added in.

This vendor tie-in extends into ETL tools (eg, you'll see lots of job requests for Informatica or AbInitio skills)

I started consulting about 6 months ago. I was very picky about which customers I took on. The ones I did turned out to be amazing sources of problems that could be whole product categories. Now I am getting ready to build my first product and I feel very confident I have my first sale lined up.

Your quote about saving 10 hours a day - try and get that as a formalised written recomendation, and do so for all future clients as well.

Also encourage your current company (assuming they aren't pissed at your decision to leave) as well as future clients to recomend you to business partners that they think you might be of use to you - the majority of the consultancy work I've done (albeit in Marketing rather than IT) has been through word-of-mouth recommendations.

I would avoid consulting firms, as in my experience employees of consulting firms generally get the shaft. Especially if you're new to the game and don't realize that clients are paying the firm 250$/hr for your time while they turn around and pay you 40$/hr. You are much better off as a freelancer if you want to get a decent hourly rate.

I would not set that as a hard fast rule, if a firm can get you your rate, then by all means use them. I have a network of firms that use me and all pay my rate. They know not to even bother if it is not at my rate. The thing is too, they know my reputation as a top caliber guy in my area and they call me in when they have a discerning client that is looking for a solutions guy. Sure a lot of firms are looking for someone who will take 40hr and that they can charge 250hr for, but almost all of them keep a stable of ringers that they can call on when they need them. What they charge their client is of no relevance to me. I have my rate and if they pay it then I could care less. To discount these firms is to cut out a massive network of well connected people that can get you work with little to no effort on your part. You just have to be very clear that you rate is non-negotiable.

Don't use an "existing consulting firm", they take half the money for providing contacts. Find your own contacts.

All your contacts will be personal. Before you quit, find and contact them from your employer's customer/vendor/peer space.

I think it would be hard to get into this field with completely custom built apps, because maintenance will kill you in the long run.

Why do you think this?

Do you know of the companies that have this need? If so, they're the first on your list for you to network into.

Promote yourself: @corin_29 is right. Get LinkedIn endorsements but more than that, consider starting a blog and putting advice on there others can use. If people find and read it and think it's useful, you have a new vehicle to tell people you're available.
