Dave has is pegged. You need 2500W type equipment. Look up sheet metal shops in your area. Anyone with a laser on one of those shops will be able to blow through those in no time. They'll also be able to bend them up as well.
I have 2 suppliers of mine that do that exact type of thing. I see things like that in stacks all over their shops all the time.
You'll probably get decent pricing around 75-100 units.
