Since you are talking about doing it in your garage, I am assuming that
you are looking for a niche. One item that I can think of is the
specialized tools that are used to make oboe and bassoon reeds. Find
some oboe players and ask to look at the tools they use to make reeds.
Work with them to come up with some improvements. And figure out a
good way to get knowledge of your improved tool to all the oboe and
bassoon players. You would probably have to set up a web site and also
send letters to various orchestras telling of your web site.

The tools are not extremely heavy and could be shipped all over the
world.
