This is most likely a custom site. If you look at the source code, you'll see that the main template file ends with .dwt, which is a Dreamweaver template extension. I'm pretty sure a Wordpress theme could be made to look like that, though.
yep. basic coding is dreamweaver. as far as the content management, I thought it might just be php/sql application...however I see their login has a catchpa so maybe is something custom + they have some paid stuff. That is a pretty nice looking little site! You could probably hire something similar on rentacoder.
