I'm sure I will not get any actual numbers, but any help would be great. Am I too high or too low? Bid ask for 2 yearly treatments of fertilizer on 9 acres of bermuda lawns. Most spreading will be on patio homes so the area is a little tight. I will be using my z-spray. I am thinking my first app will be a 25-0-5 slow release app and then the second will be 46-0-0 Normally I charge 218 per acre. I am thinking that that is a little high for the bid because of the bulk. I know that my fertilizer costs will be around 50/ac and 40/ac but am having a hard time nailing down a number for my labor. I am a one man show so I will be doing all the work.
