Thanks to you all. I got an email from them (unsolicited; no doubt they found me on Dave's ESL or Seriousteachers, both of which I recommend, though with the usual eye to caution) and had the same suspicion EVERYONE should have when total strangers with no established reputation are asking for $300 to find them a job! Some things require a middle man, but this isn't one of them. A language school is ALREADY a middle man (or you the teacher are THEIR middle man, depending on how you look at it), don't pay a middle man to get to the middle man! Do your own leg work, contact schools directly, have your paperwork in order, and use the free sites that WILL get you work. I just wish there were somewhere to report these people.
