Dear Sue,
As I have read your message, I thought I could answer and try what we could do together.
Let me tell you about the class that would be interested in giving a shot this cultural exchange, and please let me know if you're still interested:
I teach English in France, in Saint Denis (North of Paris) and the kids are around 13 years old. Some are good at English, some have some difficulties but they're all very motivated. They would like to write -- particularly the so called 'snail mails'.
Here's my email address -- please feel free to write and tell me if you've found anyone yet,
pierreFR@epals.com
Thank you very much,
My best,
pb
