I am looking for a banner ad service that not only allow me to serve ads but also sell them through said service. I've tried OpenX (both hosted and self-run) in the past, but have found it to be slow and cumbersome, and it doesn't have all of the features I want. I came across AdSpeed.com, and it seems like a pretty good service, and the pricing isn't bad. Additionally, it will serve ads and let me sell the ad space through their service. I was wondering if anyone has worked or is working with them? Also, are there any other services out there that I might be missing that will serve ads as well as let me sell ad space through there site or service? I've looked, but most of them are only for very high ranking sites, only do one or the other when it comes to serving and selling or cost a fortune. Thanks in advance!
