If you are just planning to go over to one of those cities and find a job teaching English, best of luck. As Ozgaijin and the other regulars who have responded, you will struggle to make some cash. You are better off going through the interview process at home for JETT or NOVA, and having a job waiting for you. That way your flight over there, housing, key money, etc. is all taken care of before you go. Going over cold and having to stay in a guest house sucks, because you spend so much time looking for work, and a place to live, your money can go really quickly. I think JETT pays better, at least they used to 4 or 5 years ago, but they don't cover your ticket home at the end of the contract, while NOVA does. The only problem for you is that if you go with one of the big companies, you don't really get to choose your destination. You can put down your choices, but the cities you mentioned would also be the choices for most of the other people in program who are going to the same country. Best of luck and hope it works out.
