What's involved in building a site like this? I am subscribed to an industry forum in the beverage space where people buy and sell equipment using forum posts - t's really inefficient and I often think they could use a simple marketplace site.
You should build a landing page for your idea and start testing. Spend your money to find a legit copywriter, have him write out the copy to communicate your business value prop ( clearly). You need a logo. Design, Dev, CMS ( wordpress) for payment processor use STRIPE. Make sure your site is stupid fast and keep it simple with a focus on clarity. Next, you need to start testing, testing , testing and then iterating weekly or monthly until you start making money. Try to make money from the jump.
Mate, the first thing you do when you find a forum that sells things where there is no actual market place, you build that marketplace!
Flippa is one example. There used to be a forum where users used to buy/sell websites. Forum admins saw an opportunity and built flippa (it was called something else before that, can't remember what it was) and now raking in the dough.
