Do some data analysis on your current traffic, see what converts, find some patterns on browser/os mix that makes you the most bang for your buck and start there. Slowly open it up as you start to see break even/small returns. Test test test. Split test landers, banners, optimize landers, banners. $2k isn't a lot of money to do all of what I just said but if you DON'T do any of what I just said, you may as well just give your $2k to charity and come to the same conclusion that "Paid traffic doesn't work" because that is what will happen if you buy un targeted traffic.

Good luck.
