Maybe I can find a machine shop willing to do the job for me, but then the question is how expensive will it be?
The design part could have been a nice exercise (and prototyping 1 or 2 ideas, before going metal, isn't that much of an issue nowadays where everybody and their grandma has a 3D printer). The real issue is machining. Not sure, but I think it's pretty much true anywhere that getting a one-off part machined at regular rates is usually way (waaaaay) expensive. To make it feasible, you would have to be able to do it yourself or just happen to know someone.
Nevermind then, trying to sell might really be the way to go.
