Hi I have thought about starting my own paysite, I have realised that its a much bigger project than I first thought, but im still very positive

I havent been able to find any good help material that fx. writes about the startup phase, content needs ect. But I thought I would give this board a try, im sure many of you guys can give me some tips.
Allmost all say that i should use IBILL or CCBILL as CC processors, but what about WNU or PSWBILLING.com are they no good?
I have seen that many large paysites have censored their tours, but it just looks weird, isnt it the idea to get the surfer as horny as possiple..in my oppinion its a turnoff to see those censored tour pics?
i really hope someone can help me out a little(huge) bit.
thanks
Jizar
