You should be very qualified to get a good job here, also nice to have Thai language. Most expats are getting a nice salary if they are relocated.
Also I know teachers who are getting 100-150k but they are native and have a license.
I'm COO, so everyone has chance to achieve something here. In LinkedIn they do post jobs which are open for expats, just do your best and apply, CFO - CEO - COO - CHRO - County manager roles are open for expats
