Help with husband with dementia

My husband, is physically fit but has dementia. He likes to be busy walking, going out, doing jigsaws when at home. He’s 80 years old and very friendly. He likes to talk at people but has limited verbal understanding.
I need someone who is happy to be active with him, take him out for walks or do activities with him at home, so that I can be happy to leave him. Initially I’d like someone to come here on Tuesdays from 9 until 2.
