Front end design and potential implementation

We're currently building a set of systems for receipt tracking. We have a prototype that is currently just a proof of concept. This POC is in need of design from someone with an eye for UX. The POC is simple HTML generated from a very thin JSP layer. All of the heavy lifting is done on the back end. We're talking as much about presentation as possible and any services required to support the GUI can be built (based on investment/return). All styles should be derived from the CSS. Components for the GUI should be open source jquery based components for easy integration to our thin layer (Just to keep in mind during design). Deliverable required - Logo's - Colours - Layout - Description of key Interactions - Adaptive design (Browser on a phone is just as important as on a laptop/ipad) - Styled prototype Current POC includes - Homepage - Authentication Screen - Account summary Screen - Receipt details screen - Registration flow - Profile Screen Once we've met this milestone we may reengage to help with implementation of additional features/pages beyond initial system
