I have found the best success with word of mouth and person to person interaction. I have also tried Facebook, Yelp, Google Adwords, Porch, Thumbtack, Youtube, and a website, and have found work with all but Porch and Thumbtack, but referral work is by far my biggest source. Am working on getting a van all lettered up soon, so will see if that brings anything.
Everything I got for the past 10 years or so has been word of mouth. When I started I actually put an ad in the newspaper (what's a newspaper, right?), which actually got me some work....I think that would be hopeless now, though.
