Edison Nation

EdisonNation is a web site that you need to join if you want to submit your "Great Idea"  They have on going contests.  Their concept is:

Edison Nation's team brings your voice and ideas to major U.S. companies in need of innovation and inspiration. We believe each Edison Nation member is capable of offering that spark of innovation that will become tomorrow's leading product, technology or brand name.

This is also a place to hook up to get help from other that have already done what you are about to do.

Personal Note:
This is never an easy process. Every product is different, each path to the consumer will be different.   Remember that you will have MORE PASSION for your product then anyone else.  Before you start spending money on your idea make sure you make a decision, "How far are you willing to go?  How much money can you afford to spend?  How much time are you willing to give????"
One of our products took us 8 years before we no longer had to put money into the company.  
I wish you luck!!!
