Unless you are in the South American Rain Forrest, I have to believe you have dozens of places around you that could quickly make something this simple. What material are you using?
Don't forget to include the time it takes you to find the part when evaluating whether something is cheaper to buy than make. Oh, and don't forget shipping.
I didn't note that you had mentioned a quantity so if you only need a few for a fixture this might be a source. If it's for a product of several hundreds or thousands, perhaps not.
