A word of caution about going offshore
I looked at going to Spain for my instructors rating but was able to complete the course in England by completeing the course by doing three working days a week.
When I started applying for an instructor job it was interesting that the two flying schools I approached wanted to know that I had done the course locally.
In fact at the two flying schools they would NOT have been interested had I taken the course in Spain........
Find out if the local flying schools you would want to work at feel the same way.
