Thanks Jet. Some interesting views.
To answer some of your questions.
Yes, it's a saturated market but not overly so. A lot of people have come and gone. As well, being here in France I have two things. One, I live here so have the advantage of already being here. And two, I speak French well enough that it can help in getting local knowledge etc from people. Of course, it helps in any case as speaking the local language of a country will always be preferable.
What sort of courses? From beginner to upper intermediate. I'm sure that there are many people out there who really are at the stage of "this is a camera and this is how you use it". In fact, I know there is as I'm a member of an expat forum that has a photography section.
Outside, most definitely but not exclusively. I'm a landscaper who deals with the coast and rolling landscapes. Chuck in a helping of forests/ woodlands as well as the odd bit of architecture. With things over here, I was thinking it would be a mix as here in France there is a great variety of landscapes, coasts and architecture.
As far as catering for different levels, it is important as a teacher to recognize that everyone has their own level and everyone learns in different ways. The teacher must adapt his/ her style according to the individual.
Interesting on leaving the camera at home. I've seen both and I think both has its merits.
