Been mowing city parks forever and got that covered, but there comes up a city historic cemetery about 27 ac and 5000 headstones. Looks very unkept and tough to get done in a day's time with a four-man crew. I want to talk to guys who brave those spooky cemeteries and wake up the dead with their noisy zero turns. How do you get a good solid bid on 5000 headstone trimming? The 27 ac part i can handle, but the trimming on steroids workload has me puzzled. Thanks for any help because I don't want my paycheck to cause me to shreik!
