Who do I approach in creating a prototype of a kitchen appliance idea?

I have a new idea on creating a helpful kitchen appliance. It need motors and electronics. Where can I start? Who/ what company can help me create a prototype?|||Before you approach anyone, or discuss it further.... Document it carefully; including pictures, descriptions, function, etc. Include drawings too. Once this is completed, I suggest that when you do discuss it,(actually prior to discussing) have the other person/company sign a non-disclosure and confidentially agreement. Before going too far, you may want to consider contacting a patent attorney for a brief consult. It will be worth a couple hundred bucks if you have a good idea. Be aware many people might represent themselves to help, but once they have your idea,,, your chances of making money is slim, unless you have taken steps to protect your idea. Do not describe it further online! Hope this helps.
