Part Time Caregiver For My Wife With Early Onset Alzheimer's

I'm looking for someone to provide to respite care for my wife while I exercise and run errands Sat and Sun mornings. My wife has early onset Alzheimers and is currently recovering from a hip operation. We need someone who can help maintain a safe environment, prepare and serve small meals and help with bathing. The preferred candidate would have experience with Dementia patients, like close by to Doylestown and be interested in also providing additional coverage on an as needed basis.
