Can't help you there... BUT..unless you're looking for PPC traffic?
Then you ought to test out ero-advert and blacklabelads.
Sorry to threadjack, if someone sells Finnish bannerspots/traffic.. I'm interested.
Already using the 'biggest' PPC networks like blacklabel, yahoo, google, ero-advert etc etc.. so 'maybe' looking for individuals who use openx or some other ad-software that can show geo-targeted ads.
Will pay a few cents per click, going to a sexshop.
