I love the site, but agree about the 'or's and the footer. Also, the sheet could have a larger top offset so that you can see the top of the post-its.
But I love all the details when you hover over images, like the twitter link at the bottom and the recent work images on the homepage, that idea is brilliant!
Other than that, you might do well to design your own font for the text and use cufonto load the font on everyone's browser. That would look awesome!
Good luck with the site and the business, although it seems like you've had more luck than me already, and I can see why, your designs are great! Hope this all helped!
