That's what I was thinking.i think it would be best to get one who teaches classical grades because then you have goals etc (it doesn't mean you will end up only playing classical guitar, just that you will have a good foundation)
Everyone I have spoken to recommended having one-to-one lesson instead of joining a school/class.
Questions of the day....
Do private tutors do graded stuff?
How can I be sure their not a charlatan?

I believe you mate. 



You know who you are!
