No to try and tell you what you don't already know, but conversion rate is over-rated. You should be thinking $ per visitor, a much more telling stat!
Some sponsors offer up to 35% revshare or up to $125 PPS. That should be as important at what they convert at ... oh, and of course, the CRs you see here are based on *their* traffic not yours, so what good are their numbers? You may have completely different results.
You can see a list of most of the top webcam sponsors in my sig with standard payouts. I'd recommend trying a few out first and seeing what works with your traffic.
