Sounds to me like she needs a new lawn person and you need a customer that wants the best possible lawn care. When someone starts negotiating or asking how much if this is not done, etc, they need someone else. Your name puts an image in my head of someone who maintains nice lawns. People walking by notice. In my area, it is understood that I do not cost the same as the operations where 3-5 guys jump out and have weed whackers blazing to hack down a brush patch. I have to ask myself "do I want people to see me step out of my truck and walk into this". I can do it if people see me rolling my mower onto fairway quality bermuda or zoysia. I can do it if it turns from brush patch to lawn in 60 days.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
