Product design

Hi all, I want to get an enclosure designed for my TFT display. The TFT display(it is a complete product with plastic enclosure) can be easily fitted into a cutout. The Outer size of the Display : 215 x 161 x 50(mm) Cut out can be of : 196.9 x 142.9.(mm) The rest of the dimension of outer is because of bezel. Within this enclosure, there should be a space of power supply the approx size is 100x65x25(mm). The front side of display should also have cutout to fit USB port. The box should be able to open in case if we need to do some maintenance, the opening should be easily handable, and there should be locking mechanism also. I have thought of using SS, as to give best aesthetic value, any other material is always welcome. The product should be designed for easy manufacturing. The cost of the product should be low, but if we can get the better aesthetic value, the cost won't matter much. The designer should suggest the manufacturing process. Attached are the sample drawings of the product, which I got it designed from some other designer. This is just to give you an Idea about the product not to restrict the idea.
