Project: a (mostly standard) forum-thread-post system with a mobile client designed for iOS.
Server Side: PHP + MySQL
Client: HTML/CSS/JS, enhanced with jQuery and wrapped with PhoneGap for a native application. Native coding kept to a minimum.
Both: as much open source, free software as possible (without compromising functionality). For example, PhpBB for the forum software, UserCake for user management, jQuery for the UI and transitions.
More details and project layout: please see the description and drawings in the attached Word and Excel documents.
This is my first serious outsourcing project, so I can't guarantee I got everything 100% correct the first time through. However, I will try my best to clarify or add more details should any ambiguity arise.
If you are bidding, or considering bidding, I will provide my Skype (as soon as it is allowed) for any questions, clarifications, or suggestions. Alternatively, use the vWorker messaging system.
