Anyone have experience with 24/7 home care in Pennsylvania?

My family is currently exploring options for my elderly grandmother who needs constant care, and we're based in Pennsylvania. We're considering 24/7 home care to keep her comfortable in her own house. I'm wondering if anyone here has direct experience with this type of service specifically in our state. What was your experience like with providers, and perhaps most importantly, what was the average cost of 24 hour home care that you encountered? Any insights or recommendations would be incredibly helpful for us as we make these important decisions.
