Dog-walking. My roommate used to make six figures by setting up standing dog walking appointments for affluent clients. She only worked six hours a day. Note that this was before the days of Rover which probably dominates the market in large cities, but I suspect suburbs and rural areas still need help.
I think there is definitely a place to compete against incumbent gig work companies with local alternatives. In the dog walking example, some people are willing to pay a premium to get the same person every time. Or, at my local dog park, a person brings a bunch of dogs and let's them play in the park for an hour instead of walking them.
I definitely believe this could be the path to carving out small lifestyle businesses.
Might be an opportunity there. Find repeat customers. Find dogs that play well together and aren't hard work. Specialise in very particular areas around parks that suit the operation. Decline dogs that make the process too difficult.
Letterbox drop around existing clients and parks to find more close by. Offer volume discounts for referring neighbouring dogs.
Take said dogs to park and let them run around while you operate your other businesses from your phone.
