Pet Sitter - Full-time / Part-time

I'm looking for a great sitter for 6-year-old Lab mix. I would need you to provide boarding. Non-smoker please. Needs to be the only dog in household. Fenced in yard will be easiest, but not necessary. Non aggressive, just very anxious around other dogs. She is ok with cats, if they don't want to be her friend, again anxiety, she will ignore them. Easy to handle, loves to be petted and sleep on a couch all day.
