Hello,
I have read your requirements and already started digging around for RTMP broadcasting and have a full plan on how to build your app.
I have +2 years exp in android development, developed variety of apps and used many api's ( social [ Facebook - Gmail ] and non social like [ TMBD - opencloud for online movie streaming ] , integrated with variety of backends like firebase, Parse , I also created my own api on Amazon.
I can build your app with the offered price and finish it on time , after sale support provided for one week for free .
let me know if your are interested in my offer and if I have to go beyond digging and start to run some code, I will be more than happy to hear back from you.
thanks for your time.
