I agreed to perform lawn service for a client. Quoted them a price based on a rep from the the Home Owners Associations whom I have been subcontracting with. Client paid me up front. When I get to his property, it is more that I was told. Now how do I go back and tell the client it will cost more. I will need to bring another worker with me to complete his lawn. If I do it myself it will take at least three hours. Charging a flat fee for fertilizing is a good or bad idea. Is $25 to much or to low to charge. I use a hand held aeration. I have to walk and firmly plant it in the ground. Yes very laborous. Should I charge a flat fee of $25. I do not want to lose out to the competition that may have the equipment to do it quicker and cheaper. Thanks.
