I was responding to another posters comment, not your proposed performing arts school.
As for the performing art school...
This board is by far the best source of knowledge for "newbies" in the DR, supported by some very experienced posters. Reach out to those that you feel can help you and ignore the rest. Simple!
Network, network, network for the next 12 months in the DR, learn who's who, how the school system works, the class culture and visit as many schools and chat with as many "owners" as possible. You are going to face a lot of challenges like any new "foreigner" based business in the DR, so 12 months of hardcore, focused due diligence will pay you back, big time!
If after the above exploratory period all the right boxes are ticked, go for it.
