How can we recruit a good piano teacher?

There are music majors or art colleges in colleges and universities in your city, where you can find piano majors or teachers. This is a channel. You can also find a teacher in the local song and dance theater or symphony orchestra. The local level is definitely first-class, but the price is definitely good.

After reading your supplementary question, I know your difficulty. You can try the method of recruiting in different places. Now teachers usually have them on weekends. You can reimburse the fare. If the students are good, the fare will not be a problem.

Now some art schools here do just that.
