I need some u-channel that is an odd size. I want the stock to be about

Can I make this myself without the use of a brake while still having
right-angles? Can I have sheetmetal worker fabricate this cheaply?
What material? What tolerance? How many?

What Winston said.
If you are trying to build a channel with 1/8" long legs, and 3/8"
outside dimension, 12" long you may have a problem. The legs are too
short for a press brake. A box and pan brake will do the job, but may
need a block to act as a female form inside the channel.
Tolerance is a big issue.
If I needed to make at least 5, with +-.010", I'd make a die set from
Ironwood. Cheaper than Aluminum, can be worked with wood tools. An
Ironwood die set shaould last for a hundred parts or more.
