How many hours per session? How many sessions per week? How many sessions total? Do you travel to their house to give them the lesson or do they come to you? How old are you? Are you male or female? The last couple of questions shouldn't matter but I'm asking for people's perception. If you're competent, you could be 8 years old for all i care... I'd hire you. Also, tell us the prices you think of in your head or what people tell you.
