Exterior Door Frames

Hi all,
Looking for information on where to find exterior door setup.

I do not own an eichler (My Future Dream) but I own a house in Pacifica where most of the houses are just boxes craving for som MCM details.

I want to replace the exterior entry door with an eichler type door with 2 foot side glass. I have had no luck finding anything pre-made, does anyone have a source?
Also If I have to have it made can anyone give a good ref? Send recommendations directly to: erothenhaus AT yahoo.com

Thanks,
E
