Design the UI for a new function/process on our website

This is the first in a number of small UI design projects for our world-leading crowdfunding platform. This inital task is to design the UI for a

new function/process in our web service. The functionality has almost been completed but it has been 'designed' by our programmers. We need

someone to make it look great!
Only the design is required - implementation/coding will be done in-house.
A successful project will get much more follow-on work from us.

Ideally you need to be able to start before 15th January.
