I could really supply some input here but I'm not about to give up my ruse around here. I will suggest, however, not to deal with a company like Brockhage. Every time I see their booth at ALOA, I have a feeling that they're in the industryjust to make money. I wouldn't risk your idea, if it truly is something worthwhile, with people like that. If I were in your shoes, I would start by contacting more legitimate companies like MBA or HL Flake. Preferably, MBA because they patent and manufacture a good bit of their own tools. Mark's an outstanding person and if he sees potential in your tool then there's a good chance he'll take the necessary steps to ensure you both make a good bit of money off of it.
My 2 cents.
