How to calculate the money for Changchun home improvement electrician?

Changchun plumbers work according to the bathroom. Generally, a bathroom costs 200 yuan, and an electrician costs 8 yuan a meter. Ditching costs about 5 yuan. Carpenter's ceiling is 35-50 square meters (depending on the construction difficulty), and bricklayer's tile is 25-45 yuan (ordinary brick, small brick and mosaic may be more expensive! ) The cost of oil workers scraping and brushing latex paint is about 10 yuan, about 1 m2. I'm talking about the price of manual workers. It is not recommended to find road casual workers. They are cheaper, but don't talk about quality!
