600,000 FB and Twitter unique visitors per month

I have a small collection of sites that get a good bit of traffic:

Facebook: 15k uv/day

Twitter: 5k uv/day

Traffic is from all over, with roughly 40% being US.

If you have something that needs this kind of traffic please PM me to discuss JV options.

Thank you for all of the PM's.

To update this thread, I'm not interested in Adsense or CPA offers (via tradional methods). I'm trying to exceed the current low $xx,xxx earnings per month.
