I know this thread is a bit old and the OP most likely has cards in hand by now, but I wanted to echo the suggestion above of finding an artist to design a card for you. Those guys are efficient, experienced, and pretty cheap. You probably already have a friend who is versed in graphics who would probably do a design up for free for you.
My site of choice for business cards is printsmadeeasy.com. I use the two-sided cards. Logo and info on one side, nice snake pic on the other.
