I am great with 3D modeling using AutoCAD and Solidworks for complex objects. The image that you attached is fairly simple and can be done accurately and fast. For better precision, I would be using solidworks on this one, which I will be able to produce any output format like the dwg.
I am new to Freelancer.com so you won't see any history of me in this website. However, I have worked several hours in oDesk.com. You may check my background in oDesk, my name there is Earl Mark J.
Hope to hear from you soon.
