Hi Jim,
Because our email communication is prolonged, I guess you are busy interviewing other piano teachers, which is fine.
However, to make things easier for you, I will be bluntly honest with you without any diplomatic sentence or euphemism: if you want to see a good result in your precious son's piano lesson (progresses fast and plays piano well), he should study with me. But if you only want your precious son to have something to do in his spare time, he can study with any teacher and you can choose a teacher with the cheapest fee.
Hope you make a wise decision for your son.
