whats the going rate for leaf removal? i'm talking about when the leaves are too much to just cut and bag w/ my mower. $50/hour? $100/hour? problem is, i have about 20 foreclosed homes i do bi-weekly for the bank, and they want a price before i do it, so i need to estimate how long it will take (which i'm good at), just not sure what everyone else is charging. any help?
