I think that the reason a lot of people say "But I thought it would cost £X", or "So and so can do it for £Y" is a combination of a few things:
1) we have all been brought up to think that the majority of tradesmen are rip-off merchants (like it or not!)
2) we are used to going into a shop, and paying the price on the item, not getting to the checkout and finding it has gone up
3) we are all used to Price Promises, where for high-value items it is worth shopping around and making sure you are paying the lowest price
Now, obviously these don't translate well into the world of contracted work!
Perhaps if the various trade bodies got together and had TV advertising campaigns on the virtues of using tradesmen, showed how to check they were accredited and also explained why it costs a lot of money then the number of idiots would decrease!
