Hi Kevsh! Long time no see!
The 2Much / LiveCamNetwork system may be the one he is looking for. It will run completely stand-alone so that he can have his own models, his own pricing, payouts, and his own billing. It works with just about any billing provider including CCBill and Paycom, or with a merchant account & gateway such as Netbilling. Plus, he can network it with other sites any time he likes.
