Nearly went with Check-a-Tade last year until we got down to the nitty gritty.
For an organisation that only won't tradesmen who they can check to ensure they have done a great job at various locations, they then wanted £800 just for a basic listing. If you wanted an enhanced listing, build you a web site blah blah blah it was nearly £2k.
They got told to stuff off too. But not told to stuff off with as much vigour as those who call from the Liverpool, St Helens, Manchester areas with the help the ambulance/fire/police campaigns via wall planners, diaries, colouring in books etc.
You have been warned.
