I haven't tried this online site but I heard it pays well. You will basically be a tutor to a kid via skype and the parents will pay you depends on your price. It is something you will negotiate with Parents. I heard that Math Tutors are the highest paid ones. If you are good in Math and you have patience to handle children, This could be the opportunity you are looking for. I can't give rates because that depends on the parents of the children. This is the rival of the other tutor site known as Bibbo.
