Combination Companion Care/Personal Assistant

Hi, my half-brother Matthew has social anxiety and is bipolar (he is medicated). He is in his 50s so not a senior, but he doesn't work and has been dependent on his father, Jim, to help him navigate every day life. Unfortunately, Jim is in his 80s and his cognition declining. I am trying to find someone who can primarily help Matthew with assorted tasks, such as grocery shopping, picking up medication, arranging for contractors to do repairs on his home. This may spill over into also helping Matthew's father, Jim, in terms of coordinating medical appointments and transportation to appointments. The schedule is flexible and can be adjusted for a good candidate. Services needed include: transportation, meal preparation, errands / shopping, and light housekeeping, arranging appointments and home projects.
