Door lock knobs

Yes I know there are a lot out there and in my opinion there are a lot of them out there that are not my taste either.
That being said I would prefer a stock looking one just made of polished aluminum for my car and if I am going to make some for my car then I might as well make a bunch and sell them at a very reasonable price.
It's just a thought right now and thank you greatly for your opinion.
I like your idea I would buy a set knowing they are home made and not from China.
