Argentina agencies & foreign art directors

Hey guys.

I am doing some research on where to go and work next. I always really wanted to go to
Argentina, but how would it be if I don't master spanish?

I checked Leo Burnett, Y&R, and JWT and they don't even have their work in english on their sites.

Please let me know if there is any good creative agencies in Buenos Aires where the working language is english.

Best rgds.
