Hi Paul,
I don't know if I'm the best person to offer advice on your site, but I'd be careful with the "unlimited revisions". I do illustration work professionally, and people can really take advantage of that to the point where you start really cursing the project. Also, I've heard lots of convincing evidence that it's not a good idea to list your hourly rate. It might be worth checking out thesixfigurehomestudio.com . There's some good info in there that's worth checking out.
