Strongly agree with this, over hourly or project-based. I do monthly instead of weekly, but idea is the same.
One thing I disagree with is the automatic-discount thing. Firstly, I think it's cheesy. Makes me think of street vendors saying "...But just for YOU, I have a SPECIAL price!" Secondly, I think it cheapens the perceived value. As in, "Why is Joe throwing around 20% discounts? Is he desperate? Is he not confident in his abilities?" Etc.
I think I get what he was saying. I would say the discounted number instead of saying anything about percentages. Round up whatever that number is to nearest hundred. Saying $x748.35 is your weekly rate does sound kind of sad versus $x800. As an example. Still sounds professional.
