Why not pay in btc?
And more details on what you need done and any restricions would also go a long way in helping.
I'm assuming I don't have enough to pay for these kinds of services.
As for what I need, I need to set up a site where people sign up, list things on a classifieds type format, and I get paid through upgraded listings,additional pictures, and ads. I'm also considering a ratings system and forum. When they list, I'd like a section that says what types of payment they'll accept, including Bitcoin.
use the bitcoin-otc rating system by requiring people to clearsign something when they sign up.
forum is fairly easy - but linking accounts together is a little harder (Steam/Valve don't bother for example)
the classifieds adds is not too hard either.
requesting payment in anything other than bitcoin will be the hardest thing - unless you want to pay the exorbitant fees of Paypal/Google Checkout
