This is how I would do it for my business.
Machine cost to rent per day.+50% markup.
Labor rate for me plus 1 laborer.
My cost per pallet laid$175+50%=$262.50/425 square feet installed to the customer.
I will then go back over the lawn and overseed it at a 6lbs/1K' rate to get a denser stand at a rate of $25/1K'
My guarantee is that it is healthy green grass when we left and will stay that way as long as you water, fertilize and keep the weeds out.
I've never been skydiving, but I have zoomed-in on Google Earth really fast.
