I just finished a landscape project for my eye doctor and charged his $500 bucks. But, then I use LandFX and the software is so fast that it only took me a couple hours to design the landscape and irrigation. I charged him another $500 bucks to show him how to install the drip irrigation system for his shrub beds. Hope this helps. Of course everything depends on how big the lot size is, his was maybe 150’x130′.
