Add design and admin skin to php application

Hi, I have a completed application for running contests. It is aimed at being used inside Facebook Fan Pages but it is not a Facebook app as such (which would be in the app directory). At the moment the front end design is quite poor and the admin area is also pretty bland. I need an experienced php coder with front-end design skills to apply a new admin skin (which I have) to the existing admin area and also improve the front-end view of the app. I need the work completed as soon as possible and there is repeat work for the right person. Please only apply IF you have examples of other work. Thanks
