Consider instead going to Vistaprint.com. I had some done there last fall for my home/hobby small business -- they're free, although you do pay for shipping, and they put a small ad on the back of the card (you can pay a fee to get rid of the ad.) The ad on the back of mine says "get business cards FREE at vistaprint.com".
They are thick cardstock, nicely done, and they have tons of "theme" choices. The cards look and feel much better than anything I could have made at home.
