Can anyone tell me how I can get funding for the building of my invention prototype?

Hehe what is it :D

Hello Fire:

Sure. Find an angel investor. He's an older guy who's made a lot of money in the business in which your invention is applicable. The only way I know of to find him, is to do some legwork.

It's easy to come up with an idea for a useable invention. Literally thousands of people do what you've done every day throughout the world. However, very few of these people pursue their idea, because they want someone else to test the idea at their expense. There are so few investors in the world who are willing to blow money developing someone else's "possible" invention, since many ideas are ultimately losers (failures). Therefore, start doing your own sketch and explanation, learn about each facet of the machine or idea, clearly explain it to yourself on paper, keep researching. If you do this, then you will come much closer to being able to find financial help. Without your work, you are expecting someone else to do all this legwork and at their expense, which is an impractical thing to expect of others.

There's a solution to the problem we inventors have, i.e. lack of funds to develop, search, patent, etc.
This solution is in development stage and is one of my inventions, a Foundation gathering money from manufacturers eager to be the first in the row when a good invention appears.
That amount of money is tax deductible so they are taking no risk at all.
On the other hand the inventor signs a compromise letter by which gives to the foundation a percentage of the money the invention will produce once in the market.
In the meantime the foundation takes the creation, analyzes it, makes the necessary searching of patentability, and if everything goes fine, puts the money to develop, patent, make prototypes and find the manufacturer interested in the product.

Make sure you get it patented first so nobody steals it. I have heard that invention marketing places that are there to help you WILL steal your stuff as their own.

My friend started Veggie Tales back in the late 70's and her publishing company stole it and sold it to somebody else.
She has all the copy writes and so forth but she can't find a lawyer that will help her.
So you can't trust anybody.
