First, pin down what kind of school it actually is
The word school covers tutoring centers, trade and vocational schools, language and arts academies, driving schools, and childcare or early-learning programs, and each has different economics and rules. A test-prep center and a licensed preschool are not remotely the same business. Before anything else, define exactly what is being taught, to whom, and under what regulatory category, because that determines everything from licensing to how the revenue behaves.
