Live video broadcasting, saving on server and streaming to users.

We need someone who can create simple application and show us a demo of live broadcasting, saving and streaming to multiple user. This application should work perfectly with N number of broadcaster / viewer, but for now if there will be one broadcaster then it's fine. Please bid with estimated time, amount required and web technologies going to use arround. NOTE: please do not suggest me to use any API such as youtube, facebook, twillo etc. You can suggest me broadcasting solution like OBS studi but for viewer screen it must be on web-browser. Thanks.
