House Cleaning Service Recommendation?

[Zacha341]

This is NOT something I'd look up in the yellow pages! Hah! Looking for a reference of an established, bonded professional house keeping company for an older friend living in northwest Detroit.

The house is a colonial, well kept, and in very good condition as it stands now. Monthly service needed only to maintain. There was a house keeping service used for many years but they went out of business.

Any ideas would be appreciated. Thank you.
