Have you tried any internet advertising? We ran a profitable business for two years, and a huge mode of advertising was the internet. You can set up several things for free. Yahoo Local, Craigslist, Yellow Pages Online, etc. And if you have a website, that will bring in even more business. You can get a website up and running for as little as $10 a year. You can also see about putting up pull-tab flyers on various community boards in grocery stores and maybe libraries. Hope that helps!
