Research: Profile Ad Serving Tags for US companies

I need someone to identify the tag structure / format for US adserving companies. We are trying to figure out which ad serving company is providing advertising to US publisher sites. There are about 10 major US adserving companies (Casale Media, [login to view URL], Blue Lithium, Tribal Fusion, Google (Adsense), Tribal Fusion, ValueClick, 24/7 RealMedia, Burst! media, aQuantive). The project would entail looking at major US publishers, finding the advertising tags for banner ads, pop-ups, etc for any 5 of the above companies. I don't care which five of the list of Ad serving companies. This is a research project, but the person for this job must be able to understand HTML source code and be able to identify tags. Ideally, the person would have familiarity with advertising tags. There would likely be follow-on work for the person who does this project. The output should include the tag structure, which site the ad can be observed on, what the advertisement is (banner ad, text, video ad, pop-up). I have attached a list of publishers to use a starting point for finding advertisements and, by viewing the source code, the ad serving tag.
