Sure, if you are willing to open up your home to another person, a
live-in might work out, but that person would still need to be able to work around your schedule. So maybe someone who works part-time in another job w/flexible hours or a student taking online courses, perhaps??
Or you could peruse Care.com and/or Sittercity.com and advertise your job and it's hours, etc. See how many responses you get.
Maybe a stay-at-home mother looking to make some extra spending money or a retired woman or even someone on SSI/Disability may be a good candidate.
You need to put the word out there and see what you can find.
Good Luck.
