I would call/email the nearest university. They will either have a teacher for you, or a good person that can put you in contact with someone. I don't know if I would trust the yellow pages, they haven't ever been good to me. There is also a MTNA (Music Teachers National Association) website where you can locate nationally certified teachers. Also, look up the local music store. Altough I don't recommend taking lesson there, they could also put you in touch with someone.
