Something a little bit different
I didn't want to do something that has been done before, so my entry might be way out in left or right field, but at least it is original and far from plain. Let me know if you need any other work done. I incorporated a QR code into the Back side of the card because you have a lot of information there, and there is plenty of space to put more information into that QR business Card as well. The Pintrest link just took me the the Pintrest home page (maybe because I don't have a Pintrest) not sure if that was intentional, I would be willing to test out your site and fix anything that is not completely correct.
