Portal Software Revamp

WJP Software Limited developed a portal based system for a number of client. The portal was simple, and allowed registered users to login, view contacts, write global messages to each other, save meeting documents in once space etc. The software was written in PHP with MYSQL. WJP Software Limited are now looking to upgrade this software, and develop the user interface to make it more friendly, ideally using bootstrap and jquery ui. And design the interface with responsive design in mind (i.e. Mobile and Tablet interfaces) Alongside this we would like to develop the functionality of the system to improve the document upload and storage section of the site, while still maintaining the simple interfaces.
