Business cards are about as close to a zero marketing budget as you can get. In your business, in most for that matter, word-of-mouth marketing can be the best way to develop business. First, though, you have to get some customers who can then refer you to others.

The key is to talk up your business to everyone - people you talk to on the phone, run into at the supermarket, everywhere. Carry your business cards with you everywhere. You never know who might need your service, or know someone who does.

Bumper stickers, window decals, and imprinted pens with your business name, a description (that's essential if the business name isn't self-explanatory) and phone number are other very inexpensive marketing tools.
