I have a daughter that is in dance and there are likely dance schools near you that could use your assistance. It might pay some $, but more importantly would give you experience in how the school operates, how they get their choreography, how they motivate the kids. I assume you have the ability to dance which is a piece of the puzzle in your career. But the business model and operations of teaching these kids is something that might not be covered in a classroom. Try to find a way to observe it first hand.
