This will be my first bid on a landscape installation and hope to be in the ballpark with it. Also just guessing how long it will take. I hope some of you can give me an idea how long. I will try and explain the job to be done the best that i can. I will be installing white marble rock, removing turf, laying down liner, and the black plastic edging. I plan to rent a sod cutter to take out 18inchs around the perimeter of the sides and back of the house. 50Ft down one side of the house and another 50Ft on the other and 37ft across the back. Estimate on job $375 for 200cubic Ft of white deco marble rock $37 for rental of sod cutter 2 Hrs $60 edging $50 for liner $500 labor 2 guys 10hrs $1022 Total Does the time frame look about right? Thank you for your input!
