Study abroad

The only thing I know of would be programs through a local college or university but you'd have to be a student, although if you take spanish classes there, that's really all that would be required, I'd think. Usually the career advisor handles those sort of things. I don't know if this is entirely helpful but even if that's not what you're looking for, someone in the foreign language department at your closest college or university might have suggestions for you as far as reputable companies.
