I'd say the best way to figure this fore one's own self is too go to an area you can "test" with a measured size of say 100 feet .... do the job .... time it .... compare it to ones own hourly cost n ya got a real number which you can confirm ... do this a couple of time in other areas ... mix up the results ..... get an "average" time n off ya go
thanx... same here for most areas. this one is to steep to mow and rough. must be line trimmed. some guys must have prices per sq. fott for this type of area? several of our properties have areas that can't be mowed, but very small.
Well, I have formulas for linear footage trimming and edging...
But I don't have formulas per say for mowing banks and such with a trimmer.
I do enough of this work that I just figure the mowing, trimming and edging, then throw on an extra weekly amount for mowing with the trimmer. In other words I know about how long such a place will take me and I charge through the nose for it. I go $1-$2 per minute depending on volume and site difficulty... and I guess some of that comes from the fact that "I" am doing it personally.
