Looking for an exchange with a German boy over this coming summer

Hi, I’m Justin Knight 15 years old, leaving in Geneva, Switzerland. I have been learning German language for 2 years and I’m now looking for an exchange with a German boy who wants to learn French or English (I come from a bilingual family).Ideally, I’m looking for an exchange for this coming summer. I would like to develop a long term friendship with the boy while learning German. There is also a possibility for the boy to join my school (French speaking)for a given period during the year.
