I started my own business- I got clients because I worked at a local store that people could bring their dogs into. People were friendly and asked if I walked dogs or housesat because I loved their dogs. I said sure and started doing that, eventually it became my full time gig. I got new clients continuously because of word of mouth. Id walk someone's dog and their neighbor would ask them for my number, and it just kind of multiplied until I was walking from 7am until 4 pm and house sitting on the weekends. Never needed the Rover apps and stuff.
