I've factored that in already as best as I can. I'm not sure what expense will go up considerably without my profit margin also going up as well. I currently have most of the equipment to start a second crew minus the vehicle and a couple trimmers. It is currently my backup equipment. If I had enough work for a second crew, the added expenses should in theory pay for itself. If there are any specifics of what to look out for, I'd be interested in hearing.What will you do when your expenses start to go up as you grow, and you are not charging enough?
