Build a Website using WebRTC and wrap it in a container so it can also be mobile app

I want to build a website which has all the same features as the VOIP application Skype, but I want it built using WEBRTC. If you have experience in WEBRTC please let me know, it will be vital for this project. The website should allow a user to create an account, add contacts, view contacts, initiate a text chat, video chat, or voice chat, also group calls..etc These are all functions of WEBRTC today. I want the site to be wrapped in a mobile container so that it can be used on mobile phones as an app also. I have already designed some mockups of what the screens should look like. I have also included data flows, database design schema. I will also offer 5% equity in the company to the developer who builds this.I already have clients who want to use it and have requested me to build it, so we can take this startup to revenue very quickly once its built.
