Looking for a mobile app screen design

Design details: Hi, We are looking for a social networking mobile app screen design.. The screen could be up to 48 screens but the design are very similar and so each other of them doesn't require a separate design. Please only bid if you are expert professional and have very good idea in color combination and Icons. We have some wire frame and mockup to give you idea of what we are looking for.
The designs features are chating windows, video calling, audio calling, video message, audio message, group chating, payment, home screen, welcome, invite, search, files sharing and etc.

Thanks
Ideas for the visual style: Social networking
