Hey everyone, I have a quick question for anyone knowledgeable. I'm a publisher of a midsized arts / culture website and am looking for an ad sales rep company to partner with (Gorilla Nation is an example of the kind of company I'm looking for). Our traffic is around 300-400 thousand impressions per month (which is under the Gorilla Nation threshold). We have a high end audience, so would prefer a agency with experience or specialty in luxury / culture advertising sales. Does anyone know of some good companies they could recommend? I'm in the U.S., if that helps.
