Build Business Directory Website

We are building a comprehensive business directory for a major metropolitan area. I am currently designing and populating the db schema. Need a professional to create a user interface. The design layout already exists, so this project will concentrate on php and ajax scripts to deliver the content to the user. I also need a cms to ease data entry. There is a current cms which can be converted for this use, you just need to create the appropriate SQL queries. This can develop into a long-term relationship, as there will be many extra features added into this site. This phase will include: scripting a category menu which resembles amazon's. results list page filter results by several criteria business profile page cms rework altering mySQL db as necessary to accomplish the goals of the project (adding columns I didn't foresee, and other minor db work) Future phases will include the need for Google Maps API, paypal API, and Mobile App.
