Here's the problem with it all, tradesmen are all too eager to undercut each other for some reason. There's so much work, especially for trades that require a license that anyone that isn't charging premium money is a fool. And there's lots of foolish tradesmen with short term thinking and eager to sell their services as a low price option. Often with low price work to boot.

You rarely see older guys going for cheap and it's because they know it's a foolish thing to do.
