Clip prototype

I am in the process of developing a plastic clip (similar to a badge clip). I have 2D CAD drawings of the proposed clip. The clip will contain a metal spring and rivet. I need a prototype of this product made in either a child-friendly hard silicone or plastic. It is for a children's product so the final clip to be manufactured must be CPSIA compliant (I live in CA so it must comply with our strict laws).
