HPI I think you would be helping yourself by asking for "A sitdown" and explaing yor current equipment and manpower status to the manegment. Then explain you would like to service the property and the rewarding challenge for having an opportunity. They have a price in mind ....not maybe they do. You can estimate all day on time to service,equip needed, manpower needs etc. This is late season ask for a chance to perform the task and be conservative on your price and explain why...Its a BIG JOB for you..be honest.
This is like Turf Mowing the equivalent of 56 yards at an half acre each. You are bound to have problems but at the end of at least one servvice you will have a vast wealth of experience on large properties.
I would charge (never done this large job) $885.11 per event. Take extra blades, belts, air pumps and tools. The next morning have some Aleve on the night stand.
