This is an .iso download. It is very simple. You download the OS and burn it to a DVD. There are like 100 or more free .iso burners. Your Microsoft Activation Code comes with it. I didn't look but some of the ones that come as an .iso download, also ship with an actual DVD for a few dollars extra.
If you need help making the DVD, I would be more than happy to remote in and help you with it.
