sample box/base

I got a sample box made finally over last weekend. I gave it to a local carpenter/furniture maker. He charged me Rs.500 for it(started with Rs.800 and ended up at Rs.500). He said it costs more because he had to buy an entire 8*4 sheet of MDF for my tiny box. I wasnt too happy with the box. I told him exactly how i wanted the pieces to fit in the grooves but none fit. He said the blade that the grooves were cut with, were of only 2mm and 5 mm so he passed the 2 mm blade twice but it still needed to be sanded for the pieces to fit well. It wasnt finished. The box was made with MDF and ply for the base. The hinges were of a bad quality, etc.
