Where can I find a good contractor?

The profession developed during the 19th century from the earlier "Measurer", a specialist tradesman (often a guild member), who prepared standardised schedules for a building project in which all of the construction materials, labour activities and the like were quantified and against which competing builders could submit priced tenders. Because the tenders were each based on the same schedule of information, they would be easily compared to find the most suitable candidate.
