What is the most successful means to advertise for an in-home caregiver outside of an agency?

In the state of Georgia. I have not had success with agencies ..... they are expensive, do not keep their promises and send immature, irresponsible young caregivers.

I have posted ads at libraries and churches, and now will have an ad in a local small newspaper.

My mother needs minimal physical assistance....help with shoes and socks, light cooking, light cleaning, companionship, monitoring when walking with the walker.

Any input would be appreciated. Thank You.
