I have product idea. I have two engineers that created my product on cad. I have a blue print and exact measurements. Now how do I get the actual protype of my product. Who should I contact to actually create my product. Or how should I attain the parts to create it without jeopardizing my idea.

Have the pieces done by separate fabricators and do the final assembly yourself.:-)

Distribute your work on some of your task workers and build them your self so you can have your mindset on your given plan that you want to do.
