Babysitter Needed for my Children - Full-time / Part-time

We are considering a mothers helper three to four days a week (depending on pricing) for our twins. Were expecting them to arrive late Aug/early Sept, and would need help starting in Dec or Jan. I have an older daughter, 4, who will be in daycare T, W, Th, and a dog that will be in daycare in those days, too. I work from home.
