Just about everyone is looking for cheaper prices online. I don't promote installations on Craigslist, just service work. In my evaluation of marketing online install leads are cheap seekers.I've had a few calls from there, but nothing really good. Craigslist services section has always been a place where sort of "fly-by-night", under the radar service providers post ads. Whenever I look for a service on craigslist, it's because I'm looking for a one or two man show, with much lower prices.
I'm in the same boat. I get a decent amount of business from referrals, but as I'm trying to grow, I'm not getting great results with my current marketing.Being a new contractor, I have thought about it. My only reservation is credibility.
Craigslist to me has always been associated with the word "cheap".
However if it brings in good business....I guess it can't be bad.
I do wish there was a cheaper/easier way to get ones name out. I've been hitting the streets and visiting with anyone I can to spread the word. It's a shame when I know the quality of work I do vs. some that use iffy practices.
