Ok I just got down putting a sprinkler system in my house and already have a few other jobs lined up. How exactly do you price for this stuff? hourly? or what? And also how much more do you mark up on the items you buy? 30%? My landscaping teacher said to me that to install one in my house it would be around $6000 for a 1/4 yard. I got a couple 5 acre yards to do and few 1/4 acres to do. But before I touch these what type of insurance do I need to start doing this and add more to my bottom line.
