Hello, BillMad.
I teach at a high school and in my own small "juku" school, which is in my small house. I teach English at the high school and math, English, Kanji characters and some other subjects in my juku school.
Have you ever been to Japan? Do you know anything about the situation of English education in Japan?
Basically, in Japan, very few people need to speak English. That's why most students aren't really motivated to learn the language, which is virtually a required subject in Japanese junior and senior high school. It is very hard to teach students who has little will to study it. I don't like teaching at high schools.
In Japan, anyone who desires to speak or write fluent English has to go to a language school or learn it by themselves.
The average fee of my juku school is about one thousand yen per hour.
I think it's reasonable.
In the near future, elementary school students will also have to learn English because the govenment wants Japanese people to be able to speak English. But probably it will bear no fruit.
