I've been asking my customers if they use Angie's List for anything, and the majority have said no.
I had a guy who said he found a painter on there with a coupon so he had him come out, the guy did about 3/4 of the work and then just didn't come back. Of course he had been paid up front.
He said he would never use a company for anything anymore unless they were referred to him by a friend.
I just got a call the other day from Porch.com, they work with Lowes, and you pay them $200 a month to be a member. They have 4 companies per service industry and they refer you to the homeowners that have projects going on. They have a service booklet that they put an ad in to showcase your work and all that.
I'd try it, but you have to commit to 3 months and I'm uncomfortable with that. I could see one month but no way am I giving up $600 without knowing how well it would work.
