A great place to start are with the
Guides to Spain. They provide info on visas, finding work, and the education system. I would also recommend connecting with expats through many
expat blogs in Spain. We've completed many
expat interviews in Spain that give a great idea what life & the work environment are like.
I would also recommend our new site
Expat Quotes - Spain. The writer from "
Sunshine and Siestas",
Cat Gaa, is completing the country guide with one of the first articles covering "
Teaching Jobs in Spain".
Hopefully this helps answer your questions. What other questions do you have? Does anyone have specific advice to offer?
