Best ad provider for Indian traffic?

I have a question and answer site : http://forum.ibodatabase.com , which receives more than 17000 page views per day. I need an ad provider with which I could earn some decent money. I have used media.net, qadabra, madadsmedia before : all are useless! I cant use adsense as the forum is against the guidelines.
Any suggestions? please.
