I'm preparing a bid at a local car dealership. He has two lots, one is over 86,000 sq. feet (mow-able grass) and the other is over 94,000 sq. feet. Chem lawn has had this account for several years and I was fortunate enough to get copies of their last years bid. The thing that throws me is how they charge the same amount for each application of fertilizer/chemical application. I figured that they only fertilize the display side of the properties; one being over 34k and the other over 26k. Here's what the bids were for; $135 for each application (6 step) at both properties, which figures at $43 for 5k and $3 for each additional 1k, $600 for aeration for each, $185 for grub control for each, and $108 and $135 for mowing. My question is, how do they come up with a flat rate for each fertilizer application. I do not pay the same for my chemicals and fertilizer at each step throughout the season; i.e., fertilizer w/ Barricade is considerably higher than 8-4-24. I would presume because of the volume they do they can charge this rate but it's really got me in a quandary. Just thinking out loud.
