local machine shop????

hey i was thinking of designing a yoyo or somehow legally getting a cad yoyo design that then i can send to my machine shop and get it milled???
would it be cheaper??? they can lathe metal and plastic???
or just think how cool it would be to have a completely custom yoyo :o :o :o

my grandpa owns a machine shop and i am going to make a yoyo out of titanium

cool. self-made?
