Hi , my name is Nathalie and I' ve lived my whole life in Montevideo until I moved to Usa.
I think it's a great idea to teach tesol , back in Montevideo there are important Language school : LOndon Institute , ANGLO, Berlitz that will be probably interested in having you teaching with them.
You can look on the web for the email or phone.
You can also work as an independent teacher.
Good luck
