we run own credit card processors for some our nonadult business and use CCBill and IBill in adult too. all you need to get this one just go to your bank and setting up ccma and buy necessary software. but as i can assume you'd like to provide other parties with such services (like 3rd party cc processing co's) i think it's too hard, 1st of all cause it's not totally legal, i mean visa do not like and allow such business - credit card transactions factoring. if i stupid plz spam me
