Hi
Just read your posting, sounds like you need an webRTC expert who can handle the frontend using Vue.JS.
I have a background in video chat platform building and have been doing this for 3 years, especially OpenVidu( this is full-free) & Pusher - based video/message platform building is what I specialized in.
Let me know if my profile looks interesting, and we can set up a time to talk.
Best regards,
Stefan D.
