Oh I wish I was closer!
I'm in similar situation
Need liver transplant and after 30 yrs as a nurse I found ONE friend to help but she has too much on her to travel. I recommend Care.com.
I had 21 ppl apply so got to meet and see which was a good fit
Be specific as to YOUR needs
( including travel) to weed out the Day Sitters applying. I also worked out a deal bc it's longer term so the hourly rates dont apply

Good luck with your search and a GREAT transplant result!!!! Keep us posted!
