Add Twilio video chat capability to an Angular Firebase app

Hi,

A web application I am working on requires video chat capability. I have already developed the text chat capability for multiple users. Those users can then launch a video chat from the text chat room.
The plan is to use Twilio video API for this.
You will be provided with a working angular / firebase application with basic chat capability. It has been developed up to the part that needs to launch the video. This will need to be extended to include the video chat.
There are several examples with source code provided by Twilio on how to do this and I have found the other Twilio APIs pretty easy to use in the past. Unfortunately there is not example Angular Firebase example source code but there is an Angular .NET example which should work well with a bit of tweaking.

I may be extending this myself in the future so the code needs to be readable with good commentary (comments).
You will be provided with a development Twilio account to use if you do not have one.

Basic requirements are attached as a pdf.
More detailed requirements will be provided on acceptance.

The budget is not fixed but I don't have a lot of flexibility and the price will be a factor in who is chosen.
If you have integrated Twilio video before then this would be an advantage.

Cheers,
