advice: if you're selling something, i.e. becoming a merchant, it's a REALLY good idea to sell it YOURSELF first before you go get affiliates to sell for you.
Once you introduce that human element into your advertising, shit gets very complicated.
If you think these guys are being assholes to you now, imagine how they'd treat you if you ran late on payments, or tried not paying for whatever reason.... or how some of these guys would promote your product/service.
But... if you're 100% set on using affiliates right off the bat, I would suggest using Clickbank. (clickbank.com) only because they handle the payment stuff and it's really easy to set up.
Good luck!
