Reasonably priced Storm Doors

[Joe Jor]

I am out of Westchester County, NY.  I am looking for any recommendations for Screen or Storm Doors providers that are also reasonably priced.  I will admit that the door is an unusual size (30x84) which may require a custom door. The companies I have looked at all start around $350 .  This seems very expensive for some aluminum and plexiglass.

Image is attached for what I am imagining; simple, basic, affordable.

Thanks for your thoughts and feedback.
