I am a realtor and run a lawn service in the summer. I hired a long-time friend, who is a schoolteacher, to help me. We usually switch jobs each yard-- meaning one will trim and blow while the other mows with the big mower and then alternate the next yard. I own all the equipment, pay for all the gas and repairs for the equipment, and provide drinks and occassionally lunch. As of now I am paying him 35% of what I make on each yard he helps me mow... Is this fair? Thanks for any information you may provide.
