I need a plugin for ads that does...

I went thru all the ad plugins but none of them seem to do what i want to do.

I need it to provide statistics on the dashboard (preferrably that in a way of my choosing i can share with advertisers) for advertisers of my choosing (i.e. i have a graphic and a url and voila, i've got an ad on my site for a business who wants to get in front of my readers).

Am I just missing something?
