You DO REALIZE you run the risk of getting people over at a bad time (like before/during/after the Olympic games) might create hell for them, and they just MIGHT post on public forums like these, right?

One trip up and your own reputation will be ruined, forever with some people. Please consider you plan carefully. Job agencies can be set up by anyone, really. But to actually be able to find a whole group of credible private schools is actually impossible. Do you really want to do this?
