So much of that 6,800 has to go into a warranty fund. And if we require more warranty work then is in that fund, that comes from the Cash account which further effects the bottom line. Not to mention, recalls, specially on such a new bike/car, certainly isn't unheard of.
Most inventors was hands on type of people. Ford, Wright brothers, Edison, Gates, Jobs, Vince McMahon. They didn't hire and let it to others, they was on the front lines working on the product. Least in the early days. I think in the end, he will have to put large quantities of his own $$$ up (if he has enough) or be out there in person trying to convince rich people to invest. Or perhaps use his degree in Engineering to design a gadget on Kickstarter. People love gadgets on there and them projects usually get funded and happen.
If I was him, I would much sooner fund this project by investment then by debt. I got a feeling, he will have his hands full paying them 1,500 workers, dealing with warranty work, and possible recalls without having to worry about making loan payments.
