Sounds like you want to make a tool that exists: a Di-Acro?

RE sewing machine motor:
Old sewing machines had external 1amp (1/16hp) motors that drove the machine via belt.
You can buy the whole assembly: Motor + foot pedal

Then you just need to make a belt-driven jig for the rest of it. Or multiple jigs.

DiAcro made sheet metal equipment- punches, brakes, shears, etc.

Sorry, a shop I worked with had one that was just for bending and it had interchangeable cores for different diameters of springs.
I have no idea which model it was.
But if it's something this person is doing in volume/professionally, it may be worth keeping an eye out for a used tool.
