Does anyone even use a phone book anymore, lol..
Google places is good. I get calls from all over the country from warranty places that find me online that way.
I use magnetic business cards, lettering on truck. I don't place ads in the paper anymore like I use to.
I have worked the same area for years and get a lot repeat customers or new work from word of mouth.
I think having a website for any type business is good too.
