purobably Maestronet forum would be a good place to start as they claim - in my interest area they do - to have pro players on the board and lots of other experts.

I see you do not ask about bowing so I guess you already play, in which case a book would be fine to start with.

On the otherhand try Maestronet and ask there as well
Tonight it appears to be down - they had a moderator leave and that might be whats up.
