I had contacted him a while ago about this. It's definitely a big project he's looking for... a custom website that would require HTML/CSS/XML/PHP/SQL for sure. I advised him to get some quotes from nearby web development companies, and let's just say they were what you would expect for a large custom web dev.
Very nice guy, and he might still be looking for help with this, as my skills were not enough to fulfill his needs... not sure what he decided to do, though.
