When I started, I had some basic flyers made up and taped them to doorknobs in the sub-divisions. I had my business card attached to the flyer as most will keep the card. After about two years and a great customer base, I altered my flyer to attract businesses (dentist offices, daycares, basically any place that had a database and needed backups) and went through the yellow pages. I picked out businesses in my area (there are hundreds) and made it a point to send out a flyer to at least 50 per week. The business has grown and there is a lot o repeat business. It has landed me about 30 contract to date. Hope this helps.
