Home Repair Assistance for Low Income Families?

My grand daughter is a very hard working young woman, who works everyday to pay lot rent on a trailer that she is not able to live in. She lives with very little food, no money for clothes or meds. I have paid for materials to fix it up. I have diabetes, knee replacements, and recently fell and injured my arm and it has left me unable to help her.

I need some kind charitable help. Her house needs to have about 6 sheets of drywall hung, her kitchen sink and cabinets installed and some electrical work done. Painting I maybe can do with my other arm. I don't have a lot of money left as I paid a handyman money to do some of these repairs that we had to redo, or he hadn't done at all before he skipped out. Please can someone tell me where I might get help, as she is expecting and the baby is due in Sept./Oct. We are running out of time. We live in White Marsh, Maryland area.
