Companion Care Needed

My husband is 75 with moderate Alzheimers. At this stage he still dresses and feed himself and Is mobile. He has trouble coming up with the words he wants to use and is forgetful, but still has a great sense of humor, is very social, loves to sing ( great voice). I am looking for an individual that is social and has a positive disposition, can make a simple meal, helpful with tech (phone, remote, karaoke machine) and at this stage, be good company for him while I get some respite. I am flexible on days and hours.
