You can get rid of you "$3.50 per m" theory, because it applies to absolutely NOTHING in particular. I only wish it were that simple. Your last post is a bit closer to the right track. Different places are going to pay different rates for acerage. This aplies to most every operation. A postage stamp size lawn, unfortunately for them, is going to pay aLOT more per sq. ft. than someone with a 3.5 acre spread. It doesn't seem fair, but that's just the way it works. Anyway, what I really wanted to tell you, was to keep in mind all the side work that goes with this. There are contributing factors to consider, such as the amount of trimming, (i.e.fenceline, etc.) the degree of difficulty of mowing, such as hills, tight ares where grass can't be blown, ditches, and so so on. You get the picture. So, keep these in mind as well, when you're "eyeing out" (as you put it) these places. Good luck with it!
