That site is designed by Eric Jordan, he's one of the worlds best flash designers. You can find him in plenty of Flash design books. I stumbled upon his site in 99 when I was looking through Macromedia's sites of the days. His skatejam2000 site was nomiated as a site of the day, I liked the site so I decided to look at his personal site. Since then it has changed at least 2 times but the theme of the site has been kept relatively the same.
I posted this site way back when someone was asking for some good professional flash sites to look at.
If you can find some good young talent then I doubt that they would charge you that much, the actionscripting behind the site probably isn't that advanced but the design is what makes his site stand out.
He also has some great wallpapers, which I currently use.
