Hi Paul - have you ever looked into the local AVF group in your area? I'm in one of the AVF groups in Essonne (AVF = Accueil des Villes Françaises) and we have a couple of different activities for English speakers and for French people who want to practice their English.

Not all AVFs have foreign language groups, but I would think there are lots of English speakers in the Versailles area. Here is the information:
