VBA Excel Spreadsheet/Access Database and Forms

This project requires using an Excel Spreadsheet of Access that can act as an interactive room booking, equipment, and inventory database complete with a simple user interface coded using VBA. It is understood that there are better ways to do this, but this is a unique project. A mock up is only required for demonstration purposes and must fulfill the following conditions: - 5 - 10 users must be able to use this db simultaneously - email confirmation using MS Outlook should be processed once user submits confirmation - rss-like feed to update users looking to book equipment (ie. once room has been booked, a notice is emailed out to a mailing list) - must be able to create a list of current stock, such as inventory, current bookings, etc. - transmit that current information to a webpage once webpage is called up - it must work in excel 2007 / access 2007 and the version before that (whatever that is) I am also open to other solutions, especially those using a webpage as an interface to access MS Access, for example.
