Caregiver To Practice Social Skills With My Adult Son

I'm looking for someone to engage with and practice social skills with my 21-year-old son. He is on the autism spectrum and fairly high functioning. Prefer someone young (under 30) who is into video games, D&D, anime, fantasy worlds and similar who will feel more like a peer to him than a therapist. Doesn't require formal training or skills, just someone who is kind and patient and would be able to hang out with him for 1-2 hours, 2-3 times per week to talk, play video games, watch a movie, or go out for pizza. (If you do have formal training, that's great too!) Schedule and format of "hanging out" is flexible.
