I asked my neighbor about cleaners, they use X and gave me her phone number. I called X and she did an amazing job. Turns out, X has a higher incentive to clean my house because she can synchronize timing with my neighbor and reduce her overhead cost. The arrangement has worked great for everyone, running 9 years in a row and more neighbors have joined.
I see this as an ideal win-win experience for all parties involved. It would be really nice to have a service that can create this type of experience at scale.
