Paying $150 to $200 an hour is a very small price to pay a top professional orchestral player for thier services and is worth every penny. I am an good professional player and I teach students on the side. I charge $40 to $60 an hour dependant upon where the students wants to be taught (IE his home or mine). When I play a pro gig in a jazz bar I usually get around $500 for two 90 minure sets. Remember I am an AVERAGE pro player. Classical teachers get much more for the simple reason they are the tops.
