WANTED: Laptop for elderly lady - 15" screen hopefully

Hi there, I'm looking for a laptop for 83 YO mother. Her's is no longer working and I can't afford to purchase a new one for her at this time. She uses it for work as a telemarketer for a tree company. She is still working at her age and she loves chatting with ppl she calls and gets paid per booking. It needs to be one that is up to date with Windows 10. It's a tall ask, I know, but I'm hoping some one out there might have one they would like to donate to my hardworking mother. Her name is Barbara.
