I contacted a vendor in regards to advertising their site/services on my site. He is interested and stated he is more interested in having a Pay Per Click agreement. For example he starts off with paying $100.00 and after an agreed amount of clicks are fulfilled, he has the choice to do it again or not.
SO my question is, how would I go about setting it up so I and/he will be able to see how many clicks have been fulfilled and perhaps some other useful information?
