My Father's wife (94) has just been hospitalized. Can he get help with grocery shopping and meal preparation?

My father, Bob R. is overwhelmed with the situation. He will I'm sure become exhausted from the drive to and from the hospital from the foothills to Presbyterian Hospital downtown. When I spoke with him today he specifically mentioned anxiety about going to the grocery store and I know he doesn't cook.
My son is getting married in Maine in 10 days so I am unable to fly out to help.
Can your organization provide a helper to give him a hand. He is very independent and is doing well health wise.
