as for the teaching, no need to go that far-- there are many immigrants in florida who want to learn the language. so there's a demand. maybe you don't have the credentials to teach but maybe you can tutor. i mean-- you're crazy about language. so that's probably a better entry level job for your "industry"--at least you deal in language somehow, and that love shows through, you have a natural aptitude, etc.
just a random idea. could be a million different things-- you don't need a degree to write copy
