Caregiver elderly male

Looking for standby help for my husband who is recovering from a fall with head injury. He is 6’, 230#s. We already have in-home Providence PT 2 days a week to assist him into his wheelchair then stand him at the sink while he marches in place and stands on tip toes a few times. PT wants me to do this 1-2 times a day on the days they are not there. He does mostly everything but I need a standby person in case he needs to be steadied. He will use a walker to get out of bed then pivot back into his wheelchair. He is strong, but to be safe I need another person present. Also someone to be with him when I need to run errands. Hours can be flexible and negotiable but I would like to do this twice a day, 4-5 days a week. Pay$25/hour.
