New Producer Needs Advice

Hi ... I have some pretty good amateur all digital solo content I have produced with plans for more.
All performers are over 18 yrs old, with 2257 compliant documentation.
I would like to begin selling it either on an exclusive or non-exclusive basis.
Would someone mind suggesting the best way to collect payments that are guaranteed, bank wire transfer only or something else?
Then how to deliver the the content along with the documentation?
Or should I just skip all that and sell through xtube or something?
I'm an independant in the U.S. so I can't afford to take the hits on payment processing through the likes of CCBill, etc., while attracting quality talent ike the guys in eastern europe.
Also, I have another mainstream business so I would like to avoid mixing the two activities.

Thanks In Advance
