hello!!
very interesting, I am looking for english people to improve my english, I live near Montpellier
Well Uzes is closer Nimes than Montpellier, so you may go to Airways Nimes too.
http://www.airways-formation.com/
the bad thing : their website is only in french. Maybe you can try to contact them by mail.
Esma in Montpellier is good, and all the instructors speak english, sure.
