Snow Shoveling Help

My gfs single mom hired someone to shovel her snow for the winter for $600 and was scammed. She broke her leg recently and has trouble walking, and the company bailed on her after coming for November and part of December (Prestige Landscapes out of Innisfil). She has been trying to shovel herself, but it’s very dangerous as she is not very mobile and if she falls she could reinjure herself. Is there any reasonably priced company that might pick up the job mid winter? I would like to pay someone to finish the winter for her so she can stay safe. It’s a two car driveway plus a sidewalk. Thanks everyone.

edit: she’s located in the southwest, right behind Joan of arc high school
