Not disagreeing, either, thou I *do* make my money cutting 30-dollar lawns, that's my bread and butter. Mulch and all that other stuff is great side work, but nothing is as consistent, as repetitive and as profitable as grass-cutting: Just one 3,600 dollar wb + 300-dollar weed-eater + 400-dollar blower (4,300 dollar investment) grosses 60 thousand dollars in grass cuts by the time its useful life expires.
Now that's just me.
I also have some other advice but it's for future yards of this type:
Whenever I see a yard like that, I *may* (not always) add a 5-dollar bs fee. Yes, it is a bs fee all the way around but NO it is not designed to be a rip-off: I keep running tabs on this stuff and IF a customer is paying more than what it's worth (especially one of those yards), then once this extra adds up to 100 or 200 dollars (after couple of years, maybe 3), I plan a day trip over to their site and take care of some serious work at no charge to them.
Meanwhile, even thou 100-200 doesn't really cover it, there will be other customers who will leave you before they reach this 2-3 year time-frame and that also helps pay for it.
You have no idea what that does, sneak DAT up on der azz, LOL.
