If you're really good, you can charge $50/hr for private dance lessons. Subtract the cost of the dance studio, and it's not much. If you're at the top, you might get a gig for a couple years at the ballet. Might.
That seems a little low for even a minimally qualified instructor, IME (though I suspect the form of dance has a big effect on the potential market.)

That, on the other hand, seems spot on.
