Build Phonebook Webpages

Need to develop a small website, that will be part of an intranet site. The basic functionality is to provide a phonebook that is optimized for use on a mobile device. Security will require login with two levels of access (standard & director), where some numbers can only be seen by users with 'director' level access. Once logged in, the user needs to stay logged in (cookie?) for a period of time, up to one year. This time period needs to be set globally or per user. If cookie is deleted, then re-login. One page needs to be created for standard PC browser and will be inserted to pre-existing pages. (see attached file for more info) The webserver is IIS 7, code to be ASP.Net, database is using SQL Server 2008. All source code must be provided, and results must be ready to install and run.
