Autocad - guitar amplifier chassis

I am building a guitar amp chassis and need an Autocad drawing / DXF output to use for cutting chassis. It's basically a rectangular box laid our flat and ready to bend via metal brake into chassis with screw holes. I have Autocad but am very slow at it. I would have someone do an Autocad drawing for me. I have attached: a .diagram of what I need b. an example of what this thing would look like Basically a steel chassis that is approx 18x10x3 with cut outs for transformer and tube sockets laid out flat, Would like specs both in mm and inches (decimal). Looking for someone who has designed metal box/chassis from start. This drawing will be for a flat pieces of steel that will be cut and bent into shape ans finished as a cabinet. Need to show screw holes [login to view URL] that I will provide a better more accurate diagram of what I need, It is basically like above but a bit larger with a few more tube holes. In no huge hurry for project - i can allocate 30 days. Would like to set up payments for 50% down, 5% upon completion with ability to have up to 5 changes in an order to get the project exact. If this one works out, I have several more that I would like to do.
