Good question... I actually asked one of the SPs if she does house cleaning as well. I said she can fix up my place and fix me up afterward. But, it never materialized.
I also think you will be looking at some c-rated older SPs (5-6 clients in a week). I don't think anyone would clean houses if they can make $100~120/hh all day long.
If you are trying to convert a civilian to a massage/happy-ending type, then you need your charm.
Good luck! Please share if you find some.
