A friend of mine does lawns. I think that he deals with too small of details when bidding. He's the kind of guy that suggested an extra worker so that I wouldn't wear my $2 tarp out dragging it on the ground while pruning; even though I get 6 weeks per tarp. At least in pruning, I bid by judging a yard within a 1/2 hr. On installation, I tally all the materials, add a few percent for error, and add my labor + profit margin. Now, I'm thinking of adding lawns in about 3 years or less, but after we move north again. When you folks bid small lawns and the shrub bed care - average planting within reason - do you visually "size-up" the yard and guestimate within, say, $10? Like walk through the yard and say "this one's a $150-a-monther" Or do you measure out the turf, measure out the beds, and go by formulas? How anal do you get? Have some measurements helped, but others been a waste of time?
