if it sounds too good to be true, it probably is. USD3700/month yeah right.

Here from the contract I was offered:

PROCESSING PROCEDURE
CHONG HWA HIGH SCHOOL will recommend you to the traveling Agency Company who will process all
your Malaysian working documents and flight ticket, according to School management and Malaysian
Immigration office. No any other alternative for processing your documents will be welcome.

So now you should know the next steps. They will ask you to cover those initial expenses. Their phone number also does not work. Try it.
