If you are an English teacher how about creating a set of material in printed and on a DVD that you can sell in various countries?

There's a LOT of really good quality ESL material already out there, a lot of which is created by big pubishers with lots of people and resources - making one's own, competitive materia would be tricky. But something to fill a niche...let's say I've been thinking about it already, and it's on my shortlist of projects.
