What are you trying to market exactly? Try looking on azoogle, I know they have an advertiser on there that pays out like $6.00/lead for anybody that fills out a form to look for a plastic surgeon.
Yea, what jonteezy said is right. And there an advertiser on click2sell.eu that pays more than $100 for a referal. Its a clinic based in Thailand. Btw, i tried promoting him but didn't get a single sale.
