I'm building a new inside sales team to sell our network of publishers
to cost-per-click advertisers that are already buying text ads on
google or overture.

My question is, how can i get a qualified list of these advertisers
with names and phone numbers?

I would like to provide my team a lead list with contact names, phone
numbers, email addresses for these advertisers buying on google and
overture.  Is there a company out there, or website that would help us
efficiently reach out to these advertisers.

I'm familar with infousa, dunn and bradsteeet, hoovers, onesource,
evaliant, advertising database, and justsell.com.  None of these
prospecting services seems to provide what I am looking for in regards
to the smaller more web based business.

I'd also be interested to know if there is a database of all CPC
advertisers -- even if it didn't come with contact names.  Although I
don't know if either of the following provide a majority list of CPC
advertisers, AdRelevance and HitWise could potentially be helpful.
