hi all my name is shannon. i not in the industry but i was wonder if i could ask some of you for your opinion?? i rent a house in coachella ca, when i moved in there was no grass in the back yard just dirt, but the front was very nice and complete with a sprinkler system. the back yard use to have a a few vine plants on the wall so there was a system running along the back wall. we change out the little hose sprinklers to regular ones and added a few to go through the grass but we didnt do enough so most of the grass is dieing bc its not getting enough water (which i have to redo all the grass work too). now i think i want to hire someone to lay the sprinklers all through out the yard instead of me doing bc i only have three in the middle and all the ones i have on the back wall it looks rediculose and im getting tired! there is already a system i think i would just need someone to make the trenches and lay the piping and put some heads on and cover with dirt etc roughly how much do u think it would cost i just wanted to get some of your opinions b4 i start asking so i know what im in for and i dont get ripped off. thanks for any replys i really appriciate it!!!!
