Does anyone know a script which can handle the functions of Fastclick and other CPM agencies. What I want is to allow advertise to upload their creatives to their campaigns, set price and choose criteria like category, demography, geography.... While publishers display the codes on their sites and get commission based on number of impressions. The only solution I am aware of is RevSense, but it doesn't have all the functions I need (especially categories) and is very poorly designed. If anyone known of anything similar to what I need please let me know. Thank you
