I was asked by a coworker today to price a cleanup job for him. I would be cleaning up about an acre of property and getting rid of leaves, sticks, branches,etc..... I am not sure what to charge him for it. He wants me to charge him a flat rate even though I told him that I usually just charged by the hour. What do you guys think I should charge? BTW, not sure if it is important, but he is going to rent a commercial chipper and he said the leaves can be disposed of behind his house. Thanks!!!
