Al in Florida

I'm putting together a business plan for a prospective partner to start up an adult site. I plan on doing things the "right way". Starting small with a free site and links for affilate programs to build traffic and growing slowly from there. I have access to someone who will provide me with exclusive content down the road. However, what I dont have, and havent been able to find anywhere, are estimates of revenues that could be generated from the different models. If anyone could provide me with some realistic figures it would be greatly appreciated.
