Yikes. I'm not sure I'm up for all that, you guys. More importantly, I'm not sure my mom is up for all that disruption in her home

And yes, Bruno, we typically call the ground floor the 1st floor, I was just attempting simplicity (and failing) by essentially naming them 1 and 2. She's moved into a 5-story townhome. Yup, it's pretty tall, and a freaking great place, which she deserves after the year we've had.
I'm still not sure what I'm going to do here. I really don't think I'll be able to handle that in-wall wiring job. I'll think about it.
Thanks for the help, though!
