How to get your invention manufactured

I came up with an idea for an invention and i was wondering what person i should call or email who can make me a prototype at a cheap cost!!
Plz help, i want my idea to become a product!!

Could do with a little more info, ie what processes may be required

but there are plenty of companies out there that will build you a prototype. just search for rapid prototyping.

Depending again on your invention the cost will vary, you may need to bring in investors

Email me and ill take it from u
