Hello, I had a lady from a business call me and she is looking for a small contractor such as myself for a yearly contract to take care of some trees, flower beds, fertilizing the trees? Someone else already takes care of the grass cutting. I have no idea what to charge for this? Should it be an hourly rate or fixed rate? I know I am only expected to show up either once every two weeks or once a month to weed and trim trees clean up etc. I'm going to look at the job friday but just wanted to have some ideas in mind and what to ask and look for. Any advice would be great! Thanks!!!!
