Twenty years ago, Anthony Dalle of Canberra, Australia, started mowing lawns with an old “hand-me-down” push mower and an old van. Dalle says most of his business was built by just knocking on doors during evenings and weekends. “I just went door to door in my spare time asking people if they wanted their lawns mowed or hedge work done, and it just exploded from there.” He says it soon turned out to be a full-time position for one person.
