you don't have a location problem. you have a marketing problem. if you suck at sales there you will suck at sales where ever else you go. craft your pitch more carefully and work harder for reasons on why it is better for you to mow their lawn than them. explain the benefits. Convince them it's a good idea for them to pay you to do the work. If you can't do it where you are then you won't do it where you go. it's competitive everywhere, fight or die.
