Find a worthwhile organization that's having an event and needs to print announcements, flyers and brochures. Offer to contribute the printing in exchange for placing your name at the bottom of each sheet. Cost to you is about 2 per exposure (assuming a 1-color printing job). Every time the organization hands out their flyers, they're also passing out your name. And you'll be able to mention that you're a sponsor in your own sales literature (you'll have to decide whether mentioning this is to your benefit or may detract from your own literature). More importantly, you'll gain exposure and positive public relations.
