Intranet for Web Collaboration

We require a developer/team for the creation of a collaboration-enabling website. The concept for the website is similar to [login to view URL] where companies can subscribe to and be provided with a secure private space in which to deploy collaborative tools for their employees. The desire is to engage a developer/team that not only provides the capability of delivering the application (as demonstrated through past references and work), but can also act as a consultant that can provide recommendations for the selection of the most suitable platform/tools for the development. The developer(s) should also have the ability to implement additional features to the application (through separate projects) as necessary. The website will be hosted internally on Windows 2003 server using IIS and MS-SQL. The public home site will be similar in functionality to the [login to view URL] website. We will have this website developed eventually but at current require the mechanism for the users to be able to subscribe to the service and create their private space for collaboration. The private home site will provide the following capabilities: 1. Announcements 2. Messaging 3. Calendar 4. Administration 5. Database creation/maintenance/use 6. Document Management Document management is a core requirement and needs to provide capability for checking in, checking out, undoing checkouts, etc. of most document type including word, rtf, excel, visio, etc. Document access should be restricted by privilege. Before bidding, I would suggest that you visit Intranets.com. This is similar to the functionality that we’re seeking.
