Just be aware that most TESOL jobs will not even pay that much per month. Even CELTA qualified Brits in their own country which has one of the highest costs of living in the world only get £7.50 - £11.00 per hour ($15 - 22), and the maximum number of actual teaching hours one can sensibly cope with is 22 - 24. Do the math
You'll need to go further afield to get the kind of money you need and the choice is limited: Japan, Taiwan, and S. Korea. Fortunately you are a graduate which is absolutely essential to getting any reasonably paid work. One solution is to get some university work. The salaries are low, but so is the work load, but you'll pick up plenty of private tutorials at anything up to $30 per hour.
Do be careful and be aware of TESOL course scams
