There are a lot of really awesome teachers at every test prep company. I know, I used to work at one, and was overwhelmed every day at the passion and commitment of some of my colleagues. The key is -- some. Some are great. Some aren't. You can't tell ahead of time, but later on when your scores aren't improving.... you'll know.
I would suggest that you go on Craig's list -- a lot of the tutors on there are willing to give the first session free, or at least a free first hour. Prepare for your first lesson by doing 10 or so questions from the Official Guide, and keep your notes. (If they're easy, try some harder ones -- you should have something to ask about!). Bring your OG and ask for help on the questions you found tough. A good tutor should be able to get into your head and figure out why you're getting questions wrong. A tutor who explains questions without asking YOU any questions isn't a good tutor. That's how you can tell.
Don't make your decision based solely on cost -- you get what you pay for, you know?
Look to spend between 70-120 dollars an hour if you want someone who's any good. I checked really quickly, here's the link for you to craig's list:

Good luck!
