Flutter App WebRTC

I’m looking for a flutter developer with webrtc knowledge. I have an app that has a live streaming function that lets one user broadcast live audio and video from their phone. They can than chat with viewers in a text chat along with other users watching the stream. Currently I’m using Agora but I’d like to switch to something else that’s more cost effective. Please message me so we can discuss this more - also I need this done ASAP which means I need somebody who can work this weekend and get it done. Thx
