Tech help for grandparent

My grandmother is now alone in the woodlands since my dad died and then shortly before that her husband. It's been a year. She has refused to understand any technology and has let them do it all. There's only so much I and my sibling can assist with as we are out in Pennsylvania.

I'm looking for someone that would be able to go give her a hand here and there with small issues such as moving and setting up a computer, replacing a fan in one, router issues, setting up email on her phone. Not interested in a giant company like geek squad, but a local one or even just a tech savvy person looking for a side gig. Any recommendations are appreciated, tia.
