Affiliate Plugin For Making Money Yourself

Hi,

Right now, i have a couple of websites which have a lot of visitors on them. My website doesnt sell any products, but there are similar websites that do. Now what i want is to place banners/links on my site and let my visitors go to the referral site and make a purchase there. On this purchase i want my comission. I would like to be able to have access to these statistics, so that i dont miss out on my commission or that the person im sending the visitors, scams me in the way that he lies about the actual number of purchases and wants to pays me less.

So how can i do this and im guessing there is a plugin for this?

Thanks in advance
