I've had nothing but problems with Evergreen Landscaping. They would never come and clear out the sprinklers until after it was too cold and the pipes started leaking. A friend of mine had the same problem and when she demanded they replace some of the lines they claimed she was never home when they stopped. Not only did she work from her home so she was almost always there, but they had no problem clearing my lines when I wasn't home (or at least I got a bill for it).
Maybe Miles City Greenhouse does some of this stuff, they have a really good staff. I also heard that C& T spraying had some new services and maybe able to do this kind of work too.
