The next time you are in a situation where you meet someone, maybe at a social event, or in elevator or well anywhere for that matter... turn a contact into a customer. Be prepared to give a brief key point "elevator speech" about who you are, what your business is, and what makes your business "memorable". What sets you apart? Find a way to make it fun and interesting. And remember to keep it brief and offer a business card.
This works great for family and friends you haven't talked to about your business recently. Most people prefer to do business with family and friends but if you don't remind them occasionally about what your business does they simply may not remember to contact you or to refer you to their contacts.
