Build streaming app (web and mobile)

All front-end design will be done beforehand, but need someone to setup the back-end and overall function/interactivity. Similar app as an example would be pluto.tv. The main thing is that I'm looking for someone to create a fully functional streaming app to submit to the app stores (Apple/Android) and that should work in a browser. A good example is [login to view URL] I'd like to see previous work as well or have someone quickly mock something up if possible and if they don't have previous similar work
