Sitter Job in Spirit Lake, Idaho

I work full- time and have a two year old son. I work evenings and need someone who is able to watch him in my home anywhere from 2:20pm to 11:30pm. Start times will vary based from my boyfriends work schedule each week. I will need someone Thursdays, Fridays, Sundays, and Mondays every week. We have a pet dog, he is outside most of the time and doesn't require any care. The only cleaning that needs done is if my son makes a mess, and he will need dinner prepared for him. I am looking for someone who is willing to do the job for about $550/monthly.
