$$$ per zone ...???

[JsLandscaping478]

I've been out of the irrigation game for a couple of years so I was wondering what are the prices you all charge per zone??

When I last did it, we (company I worked for) charged $350 (or so) per zone with a min of 3 zones. This was 4 yrs ago, so would $450 a zone be a good price now a days?? Just trying to get an idea. I think my current estimate would land me with a 40% profit, does this sound right??
