Encryption / SQL Server Database

Im looking for a SQL Server Guru to advise us on encryption on a database on sql server 7 / 2000. The database is a HR application, all users who will be accessing the database have an NT domain account. The DBA's are also NOT to have access to the database either. There are also several other databases that do not require encryption. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. ## Platform SQL Server 7 / 2000
