www.chickentraffic.com sells teen gallery traffic, but you will only get about 1k per day, and with 34 buyers the price per K is nearly double that of a niche with only a few buyers.

I usually recommend Choker but in this case I don't think it's really the best solution for you.
If you're happy with gallery spots, then try
www.bunnyteens.com . You should get 70k+ within a few days from a single paid listing.
