Companion Care Needed For My Mother In Lincolnwood

I'm looking for companion care for my mother in her 80s who is fully functional person and also a very sweet person. We're looking for someone to provide companionship/a friend - someone who can listen to her, interact with her, play cards with her, go for a walk with her small dog (Shih Tzu) with her around the block. You might have to make her lunch and drive her to an errand down the street - but probably not. The weekly schedule will likely differ week to week (depending on my work schedule), so the ideal candidate would need to be flexible and be located nearby. I would offer the same flexibility on our end - we would likely be able to work around a person's schedule on when they could come over and be a friend to my mom. Preferences for a female caregiver who is a non-smoker.
