Affiliate Marketing Secrets

I am working a very good payday loan affiliate program and need leads and/or guaranteed signups/applications at a cheap price. By cheap, I mean in reference to the cost of the info compared to the payout I will receive for each lead generated. Generally around $5 to $10 per is good. More if the info is good and responsive.

How do i start this up. i See there are many templates and backends i can buy for a cheap price , my only concern is how do i get all the inventory on my site is there any sites that offer all there seats to affiliated websites or something like this?
Thanks
