Help With Independently Living 90 Yo Old Dad

My 90-year-old dad who is living independently need help with daily activities and medication reminders meal preparation and light housekeeping. My sister lives nearby but will be working full-time so we need someone to check on my dad on Mondays and Fridays preferably in the afternoon because he tends to sleep late Having him come downstairs eat lunch talk if the weather is nice trying to get him to walk outside or down the driveway with his walker. We have someone coming currently Tuesday through Thursday, but need help with Monday and Fridays and possibly checking on him on Saturday or Sunday to help with medication refills would be also helpful even if it's for a couple of hours on those days. He loves golf, watching sports , the celtics and reading the Boston Globe
