Postback URL setup for affiliate programs -- 2

I need several affiliate postback urls set up, and advice on what system to use for monitoring affiliate sales via postbacks. Roughly 30-50 postback urls required. There's no system in place currently. This is a job that requires marketing/affiliate/sales based knowledge required.

You *must* have experience in postback urls/affiliate marketing, and you must include evidence of that experience in your bid.
