Seeking French High School for Virtual Exchanges but open to Exchange trips.

Hello,
I am seeking to exchange with a French high school, mostly for virtual exchanges but open to exchange trip if planned early. I am the French teacher at an elite performing arts high school in the city of Houston. The number of students taking French is small but very dedicated. I would like to allow them to get to know about French culture where they can exchange in French language and then alternate in English if you wish. My group can vary from 10 to more depending on what you have. My students range in level from A1 to low B1. I would wish one day to plan an exchange for at least a week in a French high school.
