I've got 18 & 19 year olds whipping out credit cards on Swurve, if you want to give it a shot. We're not running any in-house guerilla, but I think as others have mentioned you're not going to make bank on one profile alone.
I say throw it out w/ a few other offers and test the waters - see what does best for you. If you find the time you invest to be worth the rev keep building.
