French Tutor Sought (European)

We are looking for a tutor for conversational French—whose French is not Quebecois but European (FR/BE/CH, or "international") as the family will return to Europe in the future. Ideally twice a week, in the evening. No written homework, just conversational French for our two sons, aged 13 and 15. Both are responsible and motivated. Preference is for in-person sessions, if possible. Best regards, Pierre
