I operate a niche job board that gets about 33000 CPM per month (as of 12/30/08), I would like to sell header space (banner ads 400x60) and tower space (banner ads 500x120) to highly focused markets.
Does anyone have an estimate of what I might charge per 1000 CPM for both of these banner locations?
