Similar current college baseball players charge $20 for 30 minutes lesson and $40 for hour lessons. Bigger the town or name of the player, the higher the cost. I believe, according to NCAA (these rules change so regularly), he can only charge what is customary there so as long as they are not charging more because he is a current player and well known whatever he charges is okay. But I will agree that there are some who charge way more than they should.
