MS Visual Studio chat app - socket comms for mobile devices

Develop a simple chat application as a prototype proof of concept in Microsoft Visual Studio 2013 under Java Script - Multi-Device Hybrid App Template.

The project must compile successfully & must run in all available configurations i.e. Android, IOS, Windows Phone etc. The code structure is to be developed such that, they share a common file (for all configurations) of code to handle the above socket activity. You have to provide training to us for at least 8 hours to explain the coding topology-structure made in the project. Complete source code with detailed documentation for this project, need to be submitted on daily basis. The code & all deliverables will become our property. We expect a week time of delivery from you after we [login to view URL] us with rough milestones tied to payments. no upfront. Delays will cause problems for our project.
