I have a plow on my GMC 2500hd for my personal drive and my business. In the past I also plowed my elderly neighbors drive for free, just because that's how I was raised. We'll their gone now and the family member who owns the house asked me to continue plowing it as they are renting it out. I don't plan on doing it for free and I don't want to just give a low ball price as it is unfair to everyone doing it for a living. It is a simple drive about 80 feet by 12 feet. Usually takes me about 8 to 10 minutes. What should I tell them for a price so if he shops it I don't screw someone one else with a stupid low price. He is asking for a per push price. Thanks!
