This is an old school method, but one of the few that actually still works. The
trick is to get creative.
As you go about your daily life, be on the lookout for places where you can leave your information. Many stores have bulletin boards where you can place a tear sheet or fan out a few business cards.
Ever see the glass bowls where people are invited to drop in a business card for a chance at a free lunch? Drop your card in, or get adventurous and set up your own bowl. The cost of a lunch could land you some new hot prospects.
Again, get creative. I know of people who go to book stores, magazine racks at the grocery store, and the library to put business cards inside books and magazines that prospective partners may find of interest.
What about the lube and tune place, or where you get your hair cut? Keep an eye out for places to leave a card.
If you have any other things you have tried, feel free to leave a comment and let us know about it.
