I di believe your first error is where your looking for the door. Try a lumberyard or a "reputable" window and door dealer in your area. This should not be a hard item to find from most manufacturers. It may not be an off the shelf product and 900 to a 1000 dollars does not sound unreasonable to me for such a product in it's basic form (more option = more $). I would personally never purchase doors and or windows from HD or Lowe's unless you know exactly what your buying and can pick it up off their shelf and walk out the door with it. And under no circumstances would I tell them where I lived let alone ask them to install it.

Have you tried to order it?

HD & Lowes do not stick everything.
