Wow, great score!
I would search on the Craigs list (that's where I have seen most of these ads).
The more experience you have of course, the better but companies do take with little prior "official" teaching experience and you can also build up your record doing tutoring.
Now, only a handful of companies offers the top dollar (Veritas and
MGMAT are the only ones I know of that pay $100 per hour). Others, more like $35.
Also, it matters where you are. I know some markets have a lot of competition for these teaching jobs (NY and SF) and others (Miami) not so much. If you are in a hot market, then it will be tough landing a job like that.
