Tender elder care

Hi, I am looking for someone to spend a few days a week with my elderly mother who will be 88 in July. Her mind is good but has she difficulty walking. She walks with a walker or cane and can no longer drive. My husband and I both work and getting her to appointments is sometimes difficult. I'm looking for someone who can be a spend a few hours a day, a few days a week, taking her to appointment or just out for a drive for ice cream. I'd also like someone to check in on her when we are away for a few days or week at a time. She has a medical alert that she wears when we are not home. Even maybe stay overnight with her when we are away. We have a nice bedroom with a full bath in the lower level of our house where someone would be more than comfortable staying. Please let me know what you suggest and what your fees are. thank you so much for your time.
