Build customer interface to database for reporting

We have an existing MySQL database that holds product data and is used internally for reporting. We want to have built an online web interface to allow customers to purchase a user license to access this data (via an API shopping service), to logon, to search the data by selecting up to 5 different variable combinations, and to download results into Excel. Basic administrative functions including password reset, update user ID, etc. are also required. Developers will be provided a development instance of Tomcat 6 with full access to a MySQL database. All pages are to be written using a n-tier architecture, the front-end being JSP and middle tier being Java 5. All business logic is in Java 5. Developers will be required to extensively use Cascading Style Sheets to control Look/Feel. No in-line styles should exist. PDF images of the screen designs will be provided and must be followed precisely. A complete list of functional and technical specifications is attached.
