Before jumping off into this, have you ever taught before? You need a program to start with. You have to start with 1 2 3 4 5 and so on. You can not do it 5 1 3 6 2. If you catch my drift. It is a very long and drawn out process if all you are going to do is an hour a week. I personally would never agree to anything like that. It will be something that could go on for a very long time. I have only taught a hand full of people in my entire life. Only a few paid me, the rest were family. I would do no less than 8 hours a week, with right at 32 hours a month. I made a great deal of progress in a 6 month period. I think I charged something like $350 a month. That is not a great deal really, but it was an honest charge. That was for 2 people. I always had to have 2 people so that they could work together in learning.
The problem some of the local teachers had was young people coming to them all fired up and full of themselves, then after a few sessions become disappointed because they couldn't clean out a room full of bikers or something and stop coming. They would be late, miss days, and make every kind of dumb excuse. There is no excuse for wasting the time of another. Waste your own time, but not mine. I would ask for $1,000 cash up front. I would get all sorts of responses, but for certain they made every date for that first 3 months.
what ever you do, good luck.
