Or try to produce something that has already been made, cheaper with the same quality or better quality with the same price... eh?
Ive been looking at getting a 260z/280z carbon fiber taillight panel for some time now but from all the bad feedback from paulo, which currently is the only one producing this item, I am VERY hesitant. If you can produce a quality taillight panel for the 260/280z and sell it for the same price you would probably have buyers, or maybe for cheaper with excellent quality.
You just have to act willing and put yourself out there if you want this to happen. Communication, enthusiam,... etc.
