Once you've driven the traffic to your site, you should have endless options for monetizing it. (That really should be obvious if you've done even a small amount of research.)
What Crespozoooo recommended is a content locker, linked to an offer from Leadbolt. Basically, you would tempt your visitors with some valuable content (a video, or a document, or whatever) but 'hide' it behind a gateway. In order to get to the goodies, they would have to fill in a CPA offer. Once they do, KERCHING - you get paid!
