Taking Dog Walking/Pet Care Seriously

I've been dog walking for a while, but I recently decided to take it more seriously as my own business.
So far I've:
Created a Nextdoor business page targeting a neighborhood with higher disposable income.
Had 2 people favorite my page, but neither has reached out.
Had someone I know leave a recommendation on my page.
Started building a simple website with an About Me section, photos of me with dogs, my services, and two pricing packages.
Planned to contact local veterinary offices to see if I can leave business cards or flyers.
I'm trying to figure out what else I should be doing to get clients as quickly as possible.
Are there any marketing strategies that worked surprisingly well for you? Facebook groups, Google Business Profile, apartment complexes, groomers, referrals, paid ads, something else?
I'm not looking to become a huge company—I just want to build up a steady client base of recurring walks.
Any advice from dog walkers, pet sitters, or small business owners would be greatly appreciated!
Also I’m insured btw
