Pet Sitter Needed

I need someone to stay -- full time -- with 3 dogs & one, inside only cat. Obviously, I don't expect them to be here 24/7, but I don't like for the dogs to be left for more than 4 or 5 hours at a time. They don't have to walk the dogs on leashes. I live on a farm -- 220 acres -- & the dogs run free when they are not in the house with me. They sleep in crates, inside at night & one is crated when left in the daytime.
