Hello, we are company with team of mobile app developers here ready to go with you. Can we have a talk to start working.

Hi There! We have already developed a chat app and can develop this app for you. Thanks

What we can do to get you started with a working product to avoid all the expensive issues you will encounter with other programmers is start with an open source solution such as Jitsi mobile and connect it to your own private network of SIP servers. If your service gets popular you will need multiple servers networked together for availability. The APP itself is very easy because there are many solutions that can be built upon already.
