Companion Care Needed For My Mother In Blooming Prairie

I'm looking for companion care for my mother in her 90s. She is a lovely person, and able to take care of herself generally, but has mobility issues (she uses a walker) which makes certain parts of daily life difficult. My mother lives with my cousin, who provides her with support she needs, primarily preparing meals and light housework (such as making the bed and unloading the dishwasher). However, when my cousin goes on vacation, we need someone to help prepare her meals, do light housekeeping and run errands (such as to the grocery store or pharmacy). There may be times that we want an overnight just to make sure there is someone in the house with her (with a separate bedroom and bathroom). We have a car to use for errands. We ask that you handle your own transportation to and from my mother's house and prefer a non-smoker.
