VFE,
Sorry for the late reply - Yes is the answer. My advice would be to make sure you have the various instructor add on ratings. You should be unrestricted with the ability to teach instrument flying. Having a ME instructor rating is a bonus.
Lifestyle wise, Jerez is quite different from the rest of the costas. Although there are quite a lot of other Europeans living in this region, its style is completely Spanish (culture, cuisine and language).
If you are a career instructor where lifestyle is the most important thing, then it would be worth getting in contact.
