I pay $50/day for a pet/house sitter that stays on the premises while I'm gone. She'll feed & water 3 dogs, a flock of chickens, the barn cats who show up, and 8 horses. She'll clean stalls 2X/day, feed 2X day, collect eggs, turn the horses out and in and sleep over. I stock the fridge with her favorite stuff to eat and drink, she gets to watch all the premium channels on our big screen HD TV, and the only houseworks she does is to clean up after herself. I leave the house clean and everything done before I go and she just leaves it how she finds it.
I would expect to pay a lot more than I'm paying down here in more urban areas. We're pretty country and pay isn't as high.
