Hello OKsaddleup,
Nice username by the way!
It's best to first know where you want to teach. Once you get a job, then the school you work for should be able to point you in the right direction.
I hope you can afford schooling for your son howevever.
Tuition for International Schools is quite expensive.
You can always do a search in Google for "International Schools" in the region you want to teach in. That way you can start to get a feel for the costs involved.
