Cams.com is the best for me. I'm making a fortune with them. My number two choice is
payserve. A bit smaler company but has some good stuff
AWE is third. Haven't made me a lot but they do offer 100 bonus when you sign up with them.
Also you could try
Webcam cash
But still I recommend
Cams.com. They have the best content and pays much better than any other cam sponsor.
