English immersion with children Toulouse

I'm looking for a native English (only) baby-sitter or teacher to come to speak / learn English with my 4 and 6 yo children.

We're leaving 15 min from Toulouse in Goyrans.

Accessible by car (15min) or by Tisseo TAD119.

It would be for either 3-4 hours once a week during the weekend OR for one of two 2-hours session, after school. It's very flexible.

Ideally it could be every week for the entire scholar year.
