Regarding Sponsors

[FuckingBastard]

Well , i have a large number of sponsors which i promote them,chosen especialy after my taste.I pick them up if i like the sites from their network.
In this number of sponsors i have some bigger sponsors and some small ones and i have to say that the biggest bring me the income.I suppose that quality it sells better than some unsaturate sites.
I intend to start a little project with a lot of sites that used only ccbill, to see how it`s work with these small affiliate programs.
So,how do you pick up sponsors? What does it mean for you "a good sponsor" and "a bad sponsor"? How do you select them? I know it`s something more than regulary updates for surfers and for webmasters too.
I think this is my main problem.
