Custom web development. PHP app + Facebook integration

I have attached a more detailed description of the Project. No CSS / design / layout work is necessary. I just want the backend code. A few months ago I created an online application that helps applicants in their university application by generating a list of universities they are eligible to apply to based on their academic requirements. It is already up and running but I would like someone to redesign the system for ease of use. If you are interested, please send me your portfolio and a quote.
