If you are traveling as a family, I suggest that you look for work in Korea. They pay $2,500-$4,000 a month plus benefits such as subsidized accommodation, return airfare, and bonuses. They are always in demand of teachers. Another place that offers high salaries is Hong Kong, which pays up to $60,000 a year. Japan pays well but the cost of living is too much. Then there are countries where you won't make a lot of money but you will have a great life experience, like Thailand and Costa Rica.
All you need is a BA and a reputable TEFL/TESOL certificate or a MA in TESOL/TEFL. You probably have some sort of qualification, such as teacher's college, because of your years of experience.
The school that hires you pays for everything, including benefits and work permit/visa, so never pay a recruiter or a TEFL school for job placement service (Some schools charge up to $600).
Hope this helps,
