There were lots of people interested in the demos for An introduction to the Microsoft Web Platform (and how to do it for zip, nyada, zero cost to you) so I've posted the site that I build on my site here.
Once downloaded it should be fairly self-explanatory. It's built with Visual Web Developer 2008 Express Edition and SQL Server 2005 Express Edition both of which are free. I also recommend you download and install SQL Server Management Studio Express (also free) if you want to remain sane.
The demo code includes scripts to create the database and add some dummy data. The only other thing you'll need is some photos of properties to use as I removed the photos I was using before posting.
