What is cheapest region targeted traffic source I can get ?

Hi all, in the past I had experience creating new websites, it was and still the number of site visitors what get's G attention, specially with their domination in browsers market .
All I want they should be real visitors (no bots) and I can select countries/regions .
I don't mind/care if it's pop-up or iframe as long visitors stays couple seconds until the page fully loaded .
