Cash Management System

I am looking for designer(s) to build me the following: 1. Simple sign-up sign-in process (double opt-in). 2. Web 2.0 site which allows users to input data (date, amount, type) and store it into their tablespace. 3. Allows users to run canned reports against their data. 4. Allows users to modify layout of tables (web 2.0). This is the first phase of the project. The second phase will be to create a prototype java applet as well as webservices. I want to be able to communicate requirements through Use Case diagrams. So it is important that bidders are familiar with UML. Please ensure you have example websites (web 2.0/AJAX - only).
