I have started up a free drafting and design company. We will draw up, and even design if you do not already have a design, your idea using the latest Computer Aided Designing (C.A.D) software. Please feel free to stop by, the website is
www.thinkanddesign.com. If you have drawing that all already good, than i would say yeah, try to get someone to invest in it, but it is very hard, most company don ot like soliciatation. They way people sue these days, can you really blame them. You can also have them built yourself and shop local reatilers and they might stock them for you and you get a profit. Hope this helps
