asp.net web-based invoice application using SQL 2005 / 2008 Reporting Services

Hi
 
I am trying to find a tutorial, how to create an web-based invoice app but for the reports use SQL 2005 / 2008 Reporting Services. I can find many tutorials on the topic but they use Crystal Reports.
Does anyone have a sample or know of a site to download free sample apps or know of a tutorial that I can follow as I am new to SQL Reporting Services.
 
Thanks
 
Matthew
