If you increase the number of furniture, the return increases sharply. Looking for where they can make a kitchen setup on order (the kitchen is small, you need to turn around). The cheapest (honestly doubtful) offer is 18000r. The company has 28,000 r. Of these, 4000R is design. I refused to take my work). I decided to do it myself.
The result: I collected a kitchen for 20 thousand, but (!) In this price included oven and plate for 7000r. It took about 5000r for the material, 7000r for the tool. Approximately 1000 for transportation.
At the same time, I spent 2 hours in the evening for two weeks and two Saturdays completely on assembly. At my p/p of about 150 p. per hour it is 4000 p "time". The result is that the project has been fully paid. There is also an instrument in hand.
