Question
I need to build/install steps on a steep hill aabout 12 feet up.  I was considering digging out and putting in pavers.  I have been told there are pre-fab/cast outdoor stair insllations you can order which would make the excavating much easier. I tried to find information on the internet to no avail.  Have you ever heard of this type of installation

Sounds like there would be a much safer and quicker way to go about that daunting task.Inclines are not fun and best left for professionals,but we all know how expensive pros can be.
If I were you I would try the Google search engine and when the site comes up,type in "concrete stairs",or "concrete molds" or something like that.Google will take a direct search to the best matched sites.
Sometimes when you can't generalize the search you have to search throudifferent methods or search engines.
Try that and see where it takes you.Let me know if you can't find it anywhere.

I really have not researched that subject.My expertise is mostly plant and design,but I have seen more than a few sites with concrete statuary for the garden,but no stairways that I recall.
Hope this is helpful.
