New York City sitters: How do you advertise your services???

Hey everyone, especially those who live in NYC. Can you tell me how your advertise your business and make it stand out? There’s so many other sitters on Rover for people in NYC, plus plenty of places that have doggy day care...I’m wondering how I can get more clients. Do you advertise online anywhere? Visit dog parks? Local pages?

In case you wanna make sure you’re not giving advice to your local competition, I’m in the Bay Ridge area of Brooklyn lol.
