Evening Babysitter Needed - Full-time / Part-time

I have a 3-month-old and a 2-year-old and, on nights my husband is at work I would love someone to come and help with dinner, bath, and bedtime. I will be home with you, I'm just needing another set of hands! A typical evening would consist of walking the kids and the dogs to the park, cooking dinner, cleaning up the toys, bath time, and putting the baby/my toddler to sleep while I put the other one to sleep. My husband's schedule varies from week to week but it would be 1 to 2 nights a week (4pm-7:30pm). We do have two big Rhodesian Ridgebacks. They are 4 and 5 years old. Most of the time they just want to give kisses and lay on their beds.
