Can I hire someone to install this on my server? If so what’s the cost?

Maybe " Create your own instance" in PeerTube/ at develop · Chocobozzz/PeerTube · GitHub can help you to choose if you must install peertube (I think it’s free, but you can make a donation to help dev)
I hope it will help you, if not repost a message.

Bests regards


PS: sorry for my english, there is maybe some mistakes
