Hi guys. I'm developing a site with various components, and long story short, I will have various contributors to the site that I would like to offer compensation to. Particularly the ability to pay bloggers based upon the revenue that their writing/pages brings in. I would also like to give them the ability to sell local advertising on their pages. Is there a comprehensive advertising management tool that will allow me to run various campaigns, assign "owners", run reports, etc? Are there several scrpts that you use together to achieve this? Whats the deal?.......
