To get a tradie out to do the job, I first looked through the local yellow pages, then threw that over my shoulder as useless, then went web surfing on true local, also useless, then general google searching, and found the Trade Connect website, which has had some radio advertising as well. I punched in the job details into this site, had a call within an hour, and had the job sorted next day. Easy.
