I own a company called Lightspeed Metal Design. We do all kinds of custom fabrication but specialize in CNC plasma cutting. So for special brackets, mounts, tabs for your project you can call, text, email or PM me with your ideas. I will work with you to get the exact items and bits you are looking for.
I also do custom signs for business and personal.
1 piece or 1000's I will give you a fair price and fast turn around.
