The brand name I see in most of the trade magazines is Bilco.
They may have a list of contractors who do business in your area.

Could anyone tell me where or who I can find precast concrete
stairs
that I've seen on different home shows. The kind that a
contractor digs
a hole next to the foundation wall, cuts a hole in the wall and
then
bolts them to the wall? Anyone have any experience with this?
