build me a model & product prototypes

I'm an inventor. I am almost finished with completing my latest patent application. I require 6-8 prototypes + Cad Drawings Of a small model tool made up in metal (stainless steel maybe), the type of product that a spring clip company would make. I have a model example, I have photos & my own crude drawing available. Before commencing communication I would require my Confidentiality Agreement (NDA) signed. I cannot disclose than this @ the moment. I am in a hurry to complete this small project.
