I opened a web browser and went to the Internet Archive at http://www.archive.org. This site is also sometimes called the "Wayback Machine." It is an archive made over the years of many web sites. I entered the URL of his long-lost pages and Voila! All the pages appeared on the screen!
All he needs to do is copy the pages from http://www.archive.org and paste them into whatever HTML editor he uses for creating pages on the web site. I suspect that some reformatting will also be required.
The moral of the story is to never overlook resources that may be available to you.
You can read more about archive.org in my earlier article at http://blog.eogn.com/eastmans_online_genealogy/2009/09/the-wayback-machine.html and at http://archive.org/about/faqs.php.
