RE: ME AND MY BRIGHT IDEA
If it is indeed a new invention draw it up and apply for a patent(Sp?)
If not all you can do is pitch it to the guys who may try to buy the idea from you. Keep in mind that they could just decide to do it thier own way and leave you out. Thats why the patent is important. Unless of course you can get people to invest so you can go into production and make it yourself. Then you can try to get them to buy the existing product line.
I had an idea 10 years ago about hat/bow/gun mounted cameras to capture the hunt. Never had the money to go anywere with it. Now I can just buy one someone else came up with.
Good luck.
