I have been doing lawn care for quite a few years now. I am 22, and I started working for a local company when I was a teenager. After a few years working there I started working with my Dad in his excavating business in the summer, and I go to college all winter long. For the past few years I have been picking up weed eating jobs myself though. I have one job in particular that I do every few weeks. It is a good 4 hours worth of straight weed eating some very steep banks. I told them to pay me what it is worth to them, and I make $100 off of it. I also have a few others that I do in a similar way. However, now through my Dad's business I have picked up a few more side jobs that will be on the books. I was not sure how to go about charging for it. The one job in particular took me 6.5 hours of steady weed eating. It was a ditch that was a few hundred yards long and was VERY thick with grass, weeds, and reeds. I actually picked up a Stihl FS130R just to do this particular job (the FS45 wouldn't cut it). I will be using it a lot otherwise so I didn't mind spending the money. I went through about a gallon of fuel, and a lot of string. For the thick parts I used a metal blade to get through the reeds. What is the right way to figure out a price for this type of weed eating? Most of what I will be doing is thick drainage ditches, retention ponds, and steep banks. All the stuff that no one else wants to do. What should I be charging for this type of work? By the hour? By the job? Thanks!
