I just started a new business. http://www.unlimitedbusinesscards.com You can advertise on the back of other people's business cards. People come to the site for free business cards. Their order becomes a product on my site. Then advertisers can purchase ads on the back. Maximum of 3 advertisers on the back. I would appreciate any feedback you can give me. P.S. - I would give a 25% coupon to anyone linking (dofollow) to http://www.unlimitedbusinesscards.com on a PR 5 or higher page. P.S.S. - We also have an affiliate program. 15% first tier, 5% second tier.
