My husband has resigned his job so that he can be a stay at home dad in September, when I return to work. We really need to supplement my income and thought that evening tutoring would be a good way to do this. He is a secondary maths teacher with over 10 years experience and was thinking of charging £25 per hour for tutoring in the child's home. Does this sound reasonable? Also, when should he started advertising for students? Should he try for September, or is closer to exam time better? Ideally he is only hoping for 2-3 hours per week.
