Ningbo 100 square meter water and electricity installation budget, what is it?

Dear, in Jiangbei District of Ningbo, 100 square meter house, the budget for water and electricity decoration is not more than 7000 yuan. When it's over, it's going to be slaughtered. I don't think it's necessary to use brand-name lines, as long as they are always connected. Berry or Simon series switches are completely sufficient. It is best to find an experienced hydropower master to work.
