Yellow Pages? Seriously, phone a few local teachers and music shops and ask them. It's best to go by recommendation if you can, rather than choosing one at random. If you can't get a recommendation then make sure you aren't committed to a course of lessons. You need to be able to cancel after one or two if you don't get on with the teacher.
if you're at school they can usually help you to arrange lessons there. Usually an hour or so a week, but am sure you can go for more if you wanted. I'd say the schools music dept is probs the first port of all.
OMG piano is a great instrument^^ It's great that your school have piano classes, I took my lessons at my school , it was a course, but now I learned myself After you learned basic lessons or a few classes at school, you can be able to learn by yourself, and when you get some problems, you can ask your piano teacher
