Ran into this problem myself and this is what I did:
Put yourself together a cheap website (few dollars a month) put a bunch of photos of your work and list your website on as many search engines as you can (normally free of charge). Then make your own business cards and flyers with your website on it, put these out in every local store that will let you, such as walmart, k-mart or even some of the smaller stores. It will take a while for your website to be on the first few pages of a search engine unless you are paying them for a front page listing, but with time and determination, you will have more customers than you want.
