i work for $50 per hr solo. i could make 50k working half as many hrs as you do. don't try to kill yourself it's not worth it. you are falling into a trap that many do. what's better to have 80 customers and work 80hrs a week and charge $25 a yard or to have 40 customers and work 40hrs a week and charge $50 a yard? less is more if you price things the right way. you have less customers to keep up with, you work less hours, your expenses are less, and you make the same amount of money.
many have this false sense that more customers equals more money.
