As long as they have press dies that don't gouge your Aluminum. I'd specify surface finish otherwise you might get some unusable parts back.Sheetmetal shop can do it quickly and cheaply if it comes down to getting it done yourself.
Make sure you get 3 times or more thickness bend radius (3T BR). That will add about 1mm/0.040" to your outside width.
Most shops can't do more than 1" walls for 2" width, so if your design needs are greater, check around first.
