Data Management System

We currently have a web based application written in ASP. This app was created in-house by one of our employees who does some programming. This application captures data that is entered by our employees. The data that is entered is basic client information, like name, address, phone numbers, and information pertaining to their situation. After this information is enetered several things can occur, based on user interface. For example, dates can be genarated, form letters can be merge, and database updates and emails can be sent. What we need now is someone to re-write the application in asp.net also include some new features we like to see, like making a? form letter, user management with GUI controls, database updates based on user interface. And some other features we can describe later on.
