Colaborating with maid services

Has anyone used existing maid services as a source of prospecting? If so, what type of incentive or agreement did you arange that worked for both of you? Seems like a good fit, but I am not sure what to offer as an incentive.

I don’t have an incentive set up, but my niece has a maid service. We give each other jobs fairly regularly. Most or her clients end up being mine and many of mine end up being her clients. I just we both had more clients. lol… Anyway, seems like a good fit. Maybe a 10% cash back with each client booked? I’d be interested in seeing what other members advise.
