Try contacting the National Venture Capital Association. National Venture Capital Association (http://www.nvca.org)

Do you have a patent on it yet, to me protecting the idea,
Or have you even checked to see if someone has already patented a similar item

Is it rude or weird to ask what the gagdet is?

Have you a patent on it ?

What is the gaget, if you havint patented it yet, then you won't get funding.

Dragons den always a good option if you believe in your product.
