Call phantom screen, they manufacture and install custom sizes all the time.

"Can be mounted on the exterior or interior of house"

Interior would not work as the door itself swings in. I will send Phantom. Not inexpensive but you want a quality product,

I honestly can't see what the issue is they are usually mounted easily on the exterior frame sort of in the same place you would install a storm door. Phantom makes all kinds of different doors.

Retractable Screen Doors : CASPER SCREENDOORS (casperscreens.com) If you want a dyi solution. They custom make for your door. It really looks good and not bulky or obvious like the ones sold at home improvement stores. I have one in my interior for a outswing door that no one notice till I point it out.
