I have to agree with the other guys. There is a website called Theme Forest[^] that has a bunch of themes based on the Twitter Bootstrap framework that sometimes don't even resemble Bootstrap. They are cheap and very useable. If you are going to make money off your product, you can buy a $900 license or charge your customers and extra $15 or so whenever they sign up and then go buy another theme manually. That might help your website design a lot. If you would like me to help you along this process, I certainly can. Just let me know.
