Thailand was for many years one of the major destinations for 'TEFFLERS' However, the salaries are now among the lowest in the region, and the government is constantly introducing new regulations that make it increasingly difficult to meet Work Permit requirements. If you can fulfill all the requirements it's easy. Average salaries are about 30,000 baht / month (£600), but if you persevere, you could get double that in a good private school.
