Integrate Video chat and text chat in Android App - Webrtc - kurento

Hi I am an iOS developer(Swift), and a Project Manager for my team of developers in Android(Native), Ionic, Xamarin, React Native, Web & API Development. I am point of contact for the project till completion. 
Here the price will be confirmed once you share the complete requirement, but I can not predict it without your actual requirement.


 So please share me the complete scope of the project then only we can determine the timeline and price of the app. 

We need milestone basis payments. As like we will start the first milestone once you put the safe pay of 1st milestone's payment also. I will share the portfolio once we started the discussion. Regards Sriram & Team
