Enhance a existing Website with video calling and screen casting integration

The whole idea of the project is to make users watch video together (not youtube or open source videos). So in order to make the user experience great we want our VOD platform to be integrated with video calling and screen casting options with private room creation so the friends/family can enjoy the videos together from anywhere. This is a prototype project so we wont be providing any domain details or existing platform details. This is tested on a local server. no hosting needs to be done, The project follows as below -- 1. Index file/home page with video thumbnail 2. clicking on video thumbnail opens videoplayer in new page. 3. User has join button in the page and user generates a unique code through which other user can join the room via video call. 4. screen cast to both the users and both of them enjoy the screen together via video call. All the ideas for this project are welcome. We have a existing VOD website to which we are trying to integrate this feature. This is a prototype . So No live product is required. Bugs are fine but the deliver and the idea behind it should be clear. If you are able to deliver this be sure more projects are awaiting for you. We need a expert in JSON or JQUERY . so they can build a video calling feature along with screen casting to other user or integrate 3rd party API's
