OK, here are the cards i use for refferals, PM or e-mail me if you want the original Photoshop files
what i do is tell the customer to write their name on the card and give it to a friend. when the friend gets it, they get a small discount, and i send the customer a nice thank-you note with the $20 Cift certificate that they get as a refferal bonus. Most of my customers love the idea, even the richest of them. One of them said he loves it because of the age old quote "the rich dont get rich by spending their money" I laughed since he has more expensive cars than he could ever "need"
anyhow here is what i use for a business card and a refferal card all in one:
