UPDATE:
So, my buddy and I started doing this together two days ago.
The first night, we did 36 minutes worth of private shows and made $15.40. This was at a reduced rate, kind of like a trial period. The second night we did it, we made well over 70 dollars in a few hours, after being able to set our own price. So, total we've made over 85 dollars.
We've only spent about four hours on there...
So making about 20 bucks an hour to play with myself and my friend? I'm a college student and have never had a job that pays this much. It's work though, and you'll only get what you put in to it.
