I am 18 years old and have been mowing since i was 15. It first started out with just a couple yards. I think that i charged about $15-$20per yard. I have since realized the cost to run my equipment and the time and work it takes. I currently have about 4 yards that are worth around $45-$50. What is the best way to break the news that i need to go up on my price with out loosing the customer?
