@Gerald-And-Tiffany0 I have found it better to search for a husband/wife team who are willing to do the turnovers and maintenance rather than working with an agency. You may have to offer something more than the "going rate" to attract and keep them, but once found, they are gems that you will want to hang on to.
Ask your previous housekeeper, local churches, local storeowners, neighbors, etc. for names. Put out an ad on the next door app for your location. Be prepared to be disappointed and having to work hard looking -- that gem is out there!
