can you look for people who need a dog sitter?

Did you get Business Cards? You can pass them out to family, friends and neighbors. If you are just starting to build your business and would be interested in fostering, contact a rescue organization. I learned a lot from the Board members, volunteers and veterinarian that cared for the animals. The organization paid for the veterinary care. Some rescue organizations need short term in home fosters (1to 3 weeks). Be prepared to get attached very quickly, yet ready to let them go. That is a great way to get experience and get your name into the local area. They would probably also to pass your name and cards to others.
