We want to sell Ad space on our site...

[FIN]

We have been talking about trying to generate a little revenue on our site through Ads.
I was wondering if any of you know of any services other than Google Adsense.
What we are looking for is to be able to have a "member ads sidebar box" where members could select the amount of time they want their ad to run and upload their ad image, member ads would then rotate dynamically in this sidebar space.
Ideally this is what we are looking for but we will settle for any type of service allowing us to sell ad space on our site to our members does anyone know of any services ?

I use Project Wonderful. They use a bidding system, not a click system. I get a lot more off this method then I've ever gotten off google anything. Your key to success with this site is page views. The higher it is, and the less actual biddable ads you have, the more you make.

This is how I pay the rent here at Ning.
