agreed on the ZTR as edging tool. I would have them edge the chain link fencing, playground, and concession area. Only about 7-8 trees by the concession area, that's it. My tractor is a Kubota L3800 hydro, turbo-diesel....I can work all day on about 5 gallons of gas.
Given all the info, think it's worth it? The contract is coming up next month. Oh, and it's locked in for 2 years. Typo above...1.5 gallons per hour on a ZTR in fuel, not 3.5.
nice idea on the camera
