Hi,
We were working with industry leader adult networks for 14 years now, so we know how a real busy porn site actually works.
For payment gateways we would need to know which one you are going with, and which affiliate system you want to use. If you haven't decided on those yet, we can help you choosing the one fits your needs and budget the best.
Our bid is only for the actual website, the affiliate system should be purchased (integration is in the price), because you need an affiliate system that affiliates actually trust (Nats and PAP we suggest).
In case you're interested we can provide you with adult designs we did in the past years, just tell us your main niches yu're going with.
