Independent Trainers: Do you rent space from a local studio? If so, how much do you pay?

Most of my relationships are based on straight pay or a split, or a bonus based on number of students. There are a couple of places where I have done one on one sessions. In one of those they set the prices based on the experience level of the teacher, and the teacher pays a rental out of that fee and keeps the rest. It is about 20 dollars an hour.
