Dad and his ill wife just moved and have no help unpacking. I'm 4 states away and can't help right now, now what?

I helped my dad and his wife with their recent move. I'm out of state and disabled with a fixed income and just can't make it back a 3rd time to help them unpack and get settled in. My dad's wife is very ill and he is trying to do everything. Be a caregiver, take care of the home and try to unpack. He's 75 and I see him running on empty, but I just can't get there again for a few months. With their medical costs their budget is tight, really tight. Where can I get them some help getting unpacked and settled to relieve some of the stress he carries? They are in the Phoenix, AZ area, any suggestions?
