Most laser cutting places have folding gear, and will fold small pieces for you for next to nothing
Unfortunately, often not at laser speed
When I built boxes on the CT, I went in to a local metal place that had been recommended to get them to fold the lid of the box.
"Yeah mate, not a problem, couple of days"
2 weeks & a phone call later (Oh yeah, sorry, haven't been able to get to it yet - maybe tomorrow?), I went back in to ask & my piece of plate was still leaning up against the front of the counter where I'd left it!
"Oh, yeah, right, sorry"
It was still another few days before they rang me to say OK, it's done.
