There are quite a few 'pre-fab' estimate sheets out there for landscaping, but never been to happy with most of them. For maintenance, I think the pre-made sheets are handy, as things are more standardized and the estimates are much more repetitious.
For construction, I usually start off fresh each time using microsoft word, and describe all the work and price each section off as I go. Most of my jobs vary so much between one to another, that those standard forms just don't work. They leave you like 2 lines for plant materials, etc. I usually use a couple pages for plants alone.
Pave tech/probst has a real nice sheet for estimating paver work though. They left very little out. I got a copy when they sent a info pack to me that I requested over the internet. May want to check it out. Pave Tech's # is 1-800-247-3343.
