To answer the question about your advertising, consider this: Which of the advertisements you use, when seen by one person, is most likely to result in business? The answer may surprise you, because it's one of your least expensive and smallest ads, dozens of which will fit easily into your pocket or purse: your business card.
When you hand someone your business card, you're setting in motion a chain of contacts that can become a new branch of your network. That's why you want your card to be attention-getting, pleasing, informative, and memorable - so people will look at it, comment on it, pass it around, and keep it handy. And the next time someone needs your products or services, they'll remember you.
