Php Site Design

Hello, I work with UC Berkeley and am currently working on revamping a web-site for one of its departments. I really like the way the php site is laid out and am wondering if I could possibly get permission to use its layout as a template for our site, we would not be using any php logos or graphics, just the page layout. Our group is non-profit so we would not be making any money off of this. We could possibly even afford to pay some sort of a fee if it is necessary. Thanks, Steven
