The best way to bring in work is to do excellent work, charge fair prices, be scrupulously honest, always do just a little bit more than the customer expects, and stand behind your work. Do all that, and people will find you. Your reputation is everything.
I have people come in my shop all the time and want something sewed. In one case, a guy came in and asked me to sew a seam shut about 4 inches. I sewed it for him and refused to take any money for doing it. (I mean really, what do you charge for 10 seconds of work?) I found out later that he owned a bus service. I've since gotten thousands of dollars worth of business from him, and after he died, from his son. People remember the little things, and satisfied customers are your biggest asset.
No one lives forever, the trick is creating something that will.
