There are no doubt knowledgeable and effective tutors who are rated under master level. However if you want to charge a fee you want at least a master title. It wouldn't necessarily have to be from FIDE (an FM). Generally the higher the title the more you can get away with charging.
The exception being when you're a respected author. Famous authors could likely charge more than any unknown GM. NM Dan Heisman comes to mind.
Hello to everyone. I have heard that there is not much money to be earned from playing chess but there are possibilities to earn a decent amount from tutoring. I was just wondering what sort of rating would you need to become a tutor and any other infomation regarding this issue would be greatly appreciated.
