Hehe I'm in your shoes too kinda - used to run a pretty big site about 3 years ago, but had to put halt to it for personal reasons, so I'm starting everything again now
So far I'm giving a try to Adult Action Cash, Dating Gold (see sig), and Extreme Paychecks (<a href="http://www.extremepaychecks.com/referral=yme/index.html" target="_blank">linky with my ref here</a>).
Still in the process of tuning up a couple of sites, so no solid stats here yet but from what I've heard, those programs should do well enough to start off with
EDIT: Extreme Paychecks have a TON of premade galleries and Dating Gold has cool amateur looking content
