Hello rjcnz7,
First of all, I would like to tell you that I'm a big fun of kindle (books) , and I have one myself. I am an experienced web developer, and I've done lots of web scraping lately so this would be an easy project for me. For scraping the data from the site, I am going to use Python and BeautifulSoap module. For doing this scraping (report) weekly, it would be best to use cron-linux tool, which run the script at specific time, and if you are using windows it would be schtasks tool.
Best Regards,
Stevan
