Looking for companion sitter immediately for elderly Alzheimer's patients with 2 broken arms in rehab facility

Looking for someone to sit with very sweet 76 year old woman with Alzheimer's and dementia, not severe, while she is temporarily in rehab center and possibly where she goes from there. She will need help getting out of wheelchair to use restroom, and companionship. She weighs about 150 lbs. The place she is at is in Mansfield off of Broad near 360 but she will not be there much longer. Will probably need sitter for her where she moved as well but not sure yet. Not a full time thing as we cannot afford to pay that but possibly 4-5 hrs a day depending on rates. Need immediately.
