Townhomes... I'm talkin about the ones with the really small yards. Most don't even have a front lawn, they just have rocks or mulch. And most of these customers don't care what it looks like, just so it gets cut. 10 bucks for middle lots and 15 for end lots. Pass the flyers out with price quote and a given day of service with weekly or bi-weekly. The trick is to make them all aware that you are there every week, same day, and its only 10 bucks. Make contact with each neighbor. You'll be making $100+/hr in no time with your 21" mower.
