It's possible that there are chancers who are passing themselves off as guitar teachers.
Treat it like you would shopping around for any other service. Ask for referrals, look for feedback on the teacher concerned, try to find out if they have a high turn over of students etc etc. Try asking at the music shop you deal with - they will know teachers in the area and something of their reputations and abilities.
