Adult billing solution intergration

social engine 4 script - zend - Expierience with payment gateways is a plus. Please provide refference sites of payment gateway intergrations, but I am open to all bidders. I need an adult billing solution intergrated into my website. Currently I have paypal and o2checkout intergrated for use but neither one allows for adult websites. The final result of the intergration must function as the currently intergrated other two billing solutions. I would like to have epoch intergrated. I have a test/development site that you can develop right on prior intergration of the finished project on my main website. Full testing and debugging to be completed prior to payment. I look forward to your bids
