The business card as we know it has been around for so long, we sometimes take it for granted. It's small, portable, has a lot of information...and represents your brand. I admit, I'm a collector of business cards. I'll flip through my collection looking for someone, and I tend to notice that certain cards stand out more than others. Here are some things you might want to consider:
1) Size: ever thought about doing a size slightly smaller? Standard size is 2" x 3.5", but I've seen slightly smaller sizes such as 1 5/8" x 3". I've even seen one from a green-friendly company that was 2 1/4 x 2" (yes that's right). It says right on it "This card uses 35% less paper than the average business card."
2) Paper: You are proud of your business, show it. Why not use a heavier paper, maybe a 111# glossy cardstock. It'll sure last longer and it gives a good impression.
3) Orientation: maybe try a portrait (vertical) orientation rather than the traditional landscape one.
4) The back: I'm a big fan on white backs when I have something to write on them (where DID I meet this person, who do they know, etc.) However you could also argue that a white background is 50% wasted real estate...so the choice is yours. If you've got something compelling to say on the back, go for it.
