After seeing what the finished product would look like I would suggest
making a bender similar in concept to the link George McDuffee provided. I
would have it to use air cylinders to muscle the bend and make both bends at
the same time.

Operation would be to place EMT in bender over one die and under the other,
this bender would be vertical so parts drop freely after the bend is
completed.

So, place EMT in bender, actuate (button or pneumatic valve), bend takes a
couple seconds maybe. Shallow bend is bent down over fixed die, steeper
bend is bent up over another fixed die. When cylinders are retracted, the
end bent upward falls and the shallow bend isn't enough to hang up so it
falls freely in a box of bent handles.

This should be capable of 10 per minute, be cheap and simple to make and
control, not strain or exhaust an operator...

The part that rotate around the die to make the bend could rotate using a
trailer axle stub and hub, tapered roller bearings on the cheap, long life,
heavy duty, grease with boat trailer hub greasers.

Adjustable stops fine adjust the bend angle...

On prepared EMT, the bend operation should be nearly completed in about 8
hour per month, low labor cost. Gotta compete with them Mexicans!

Optional automated EMT cutting, loading, drilling, and assembly.

If this is clear as mud I could sketch up a concept drawing.
