Since it's not your personal business, rely on the Personal energy number and fortune element of the business itself. From there look at the computer section of the Transparency facet of your manual in regards to placement of items in the business' best directions. You could place names and such differently on each of the owner's cards, depending on their ppersonal energy numbers. Most company's generally create just one tempate. The business' fortune element will guide you regarding colors.
Here is also a small piece regarding business cards from one of the Diamond Feng Shui Newsletters:
"...When giving your business card to others, consider the following Feng Shui guidelines to attract business and enhance networking opportunities. Hold your card out with two hands and bow slightly. Or, at the least, give out your card with the right intention. Place your intention and blessing in the card so that by simply giving it to another person you will attract their business to you or attain a valuable networking opportunity.
You can also use Feng Shui with the cards you receive from others. For the cards you receive from people you want to meet again, write a short note on the back of their card, and keep it in a certain side of your wallet or purse. Place the cards of people whose names you just want to keep for your database on the other side. Enter those people into your database right away.
Invite the people you want to see again to your Facebook or LinkedIn page. Send them an email. Tell them how much you enjoyed meeting them and that you look forward to creating opportunities to work together."
