Housekeeper Needed - Full-time / Part-time

We have a 3 bed 2 bath house, and a home office. Looking for someone to come in and clean once a month. We have guests over once a week, and always clean a bit. But having someone come in once a month and cleaning a little more comprehensively than we do would be a big help to us. Were probably looking to start in August. Its my wifes birthday and Im thinking about surprising her with this.
