any good per impression banner buyers?
 

I want to sell all my ad space per impression. What are the most reliable companies out there for this?
Thanks,
Chris

ROFL I had to check the calendar to make sure it was 2010 and not 1999

No one does CPM, and if they do they wont pay you.

so i can buy CPM banners, I just cant publish them?

Not sure where you would buy banners at CPM. I see it more as a number used to compare different advertising, ads and companies.

You can try Ero Advertising
