Looking for LA based custom aluminum fabricator

Any recommendations for Los Angeles based custom aluminum fabricators? I’m looking for a local shop to fabricate some components of a chandelier design that I am working on.

The core of the light is aluminum so I am looking for a fabricator that has experience machining and welding aluminum. A number of the parts will likely be laser cut though I would expect most shops to job this out. I’m hoping to build a limited production run but I need to fully prototype the design first.
