Designer,
I would build a website for this if you don't already and host your video and other pics and info on it. You could then email companies, and with a click of a button, they could see your product. It might help where mailing the DVD it takes the person to take the initiative to play the DVD. Just a suggestion. I sure hope it gets marketed, I would buy one and keep one bow set up with it all times. Good luck and thanks for posting.
