Design a Cubed Box made with Plastic and Copper

Need a Cad Designer / Engineer to design a cubed shape box made from plastic and copper, we have three sizes based on the same design. The mechanical operation and general specs are completed we just need someone to who is innovative and component to work out the logistical details. The final concept must be cutting edge, functional, pleasing to the eye similar to a Ipad or cell phone. It needs to be durable so that if it’s dropped multiple times it will not crack, chip, or break. The inside components are made with a mix of copper and plastic; I need an engineer who can come up with cost cutting solutions while maintaining the quality to reduce the copper volume as much as possible. If you have any relevant experience please show me a sample. The more relevant your sample is to what I am doing and looking for, the better your chances are for being hired. The final product will be owned by us and all work will be done in strict confidentiality. Details of this product and non-disclosure agreement will be sent individually. The completed project must include a full color CAD drawing and a BOM, and a list of recommended manufacturers who can produce a prototype of this.
