running an affiliate program.

[sonomasnap]

I have come across a few amazing sites that do not have affiliate programs. I am talking to them about running one for them. They all use 3rd party billers that support affiliate programs. What should I get for running and promoting their programs if they start to offer an affiliate program? What do I need to provide them? What else should I be thinking about?

Thanks

p.s. Chris, you obviously have the answer. ICQ me if you are around.
