560444 drawing/product design of prototype iPhone 4 case 3D CAD

The project specs are a little loose this week but will tighten up toward the end of the month. That being said, we need an engineer in place before the project is green lighted. We need a 3D CAD drawing for a prototype iPhone 4(S) cell case that will be CNC'd from 6061 aluminum, injection molded polycarbonate, or a combination of the two. Styling is paramount and so is ergonomic design. We have a sketch-up but need to finalize some of the functionality before we hand it off. The cell case will look like a cross between the Element Vapor Comp ([login to view URL]) and the Otterbox Defender Series ([login to view URL]). Please give us an idea of the time required to create the drawing and compensation. Please contact me with any questions.
