I'm not the brightest light on the tree, but what

I'm not the brightest light on the tree, but what would be the advantage in selling anything if it's half what we think it is? He has the technology, it's pretty much paid for, he doesn't need to hire salesmen, he only has to put in a bigger front door to the business and collect the cash. Give this thing a year or two and it will be a real cash cow. Just sit back, develop new uses, tweaks, why sell?
