Where can I find someone to build a working prototype of an invention?

Answer 1

That depends entirely on the invention you are making. I have been a custom fabricator for 20 years and have made prototypes for many inventors. It is a hard thing to do to make someone else's ideas come to life and even harder when the inventor doesn't want to give out too much information.(which is almost always the case) If you want to you can e-mail me [e-mail] and try to explain some of what you need. I might be able to help you find the right people. Who knows i might be able to help you myself. Only thing i can say for sure is don't give out too much information to any one person and make your prototyper sign a disclosure agreement stating they will don't discuss it with anyone before giving them all the idea. I have signed many of these and anyone who wont is not someone to trust. There is also a disclosure document program with the us patent office allowing you to register your idea with them for only 10 bucks. It will record your idea for 1 year allowing you to protect yourself without the expense of a patent. After 1 year the records are destroyed so you have to start the patent process before then

Answer 2

My company does this. E-mail me and I can send you some info for your review.

Be careful about disclosing your idea to anyone without a non-disclosure agreement (preferably in writing).

Don't get any prototype work done in China...
