Trade show booths are another form of advertising, but in my experience their value proposition can be dodgy for small businesses like yours. You're looking at over $10,000 plus travel expenses for even the smallest booth in most cases, so you need to be pretty confident that your presence there will generate more than $10,000 in new profits. For a small business, that's a pretty tall order. And you can't just put up a booth in the corner and expect people to come dump money on your lap you need to do a lot of work before the trade show to publicize your booth to attendees, and arrange meetings with potential customers at the show ahead of time. You'll need to invest a lot of time in following up with people afterwards, as well. Often it's more cost-effective to just attend the show as an individual, and carry around a bunch of business cards for the connections you make while you're there. I like to walk around with a tablet running a demo of my software, so I can show interested parties my technology without a booth at all (be careful not to run afoul of any policies of the trade show when doing something like that your smartphone may have to do if attendees aren't permitted to bring larger items onto the show floor). You may get more value focusing your time on networking at the show, instead of manning a booth. Still, consider it carefully. In some industries (arcade games come to mind), a booth at a specific trade show is basically the only way in, so I can't provide one-size-fits-all advice on the topic. How about physical mailings? In the early stages of my company, I mined my LinkedIn network and LinkedIn groups to find people who might need my product, and were in a position to approve its purchase. I went to their company websites to get a mailing address, and sent each of them a physical brochure accompanied by a personalized, signed letter. About 10% of the people I contacted ended up purchasing my product which is an excellent return on some paper, a stamp, and a few minutes of my time! I ended up contracting a college student to help scale that effort up. Most tech companies have abandoned direct mail in favor of email campaigns but you can do both, and use the relatively empty physical mailbox of your customers as a chance to better grab their attention.
