A simple model:
Offer a webmaster program with a $150 payout per join.
Build you paysites to charge $90 per signup. (why so high? The higher it is the less people will sign up and the more people to make it to your exit sales!)
Have all exit sales go to other sponsors that offer sites for lower prices.(note: that this would also take away the worry of chargebacks because these signups are to someone elses sites.)
Another option at this point would be that these lower priced sites are some of your own that are not in the current program. (You would then get %100)
Every once in awhile throw signups to your top promoters.
Its money in the bank!
I can't believe that someone hasn't thought of it before.
