Seeking online friends for my son

Would anyone be interested in your child doing a 15 minute video call and doing a weekly penpal with my son? He is pre kindergarten this homeschool school year. He has started to write and love sending mail out to his grandparents, so I figured a penpal would be good for him. He enjoys pretend play with toys, Lego building, transportation vehicles, watching movies/ going to the movie theater, bike riding, swimming, dancing, singing kareoke, taking pictures with his camera, doing show and tells, cooking, camping, hiking, traveling by plane and train.
