I know a lot of cam girls and I don't think I know a single one dedicated enough to do 20 hours a week . . . I was going to say consistently, but I think I actually mean ever.

Useful stats, for what the OP asked, might be how many hours an average cam girl works and how much she is realistically likely to make on average.
