At this point I don't have many accounts (10). Mowing is not my full-time job, but I love to do it. My full-time job is teaching. A lady I teach with has approximately 7 acres she cuts between her home and her mom's house. She says she is sick of it, but I don't know how much she is willing to pay. It is mostly open ground with some trees and trimming around the homes. She won't be picky, or in other words, it doesn't have to be perfect. She just wants to make sure the grass is cut on a weekly basis. I don't want to blow her away with a price, but I would like to get the job and make some decent money from her. I think once she sees what I can do she would be pleased. But, like I said, I'm fairly new to this. I have only bid small jobs; nothing this big. Give me some help. If it matters, I have good equipment. I run a John Deere z-track 737 w/ a 54 in. cut. I'm guessing a job like this, by myself, might take 4-5 hours. Is that an accurate estimate?
