Part-Time Nanny For Infant

My husband and I are looking for a part time nanny for our 4-month-old son. We both work remotely from home and I attend classes in East Lansing on Wednesdays from 2:00 to 7:00 p.m. We are hoping to find someone who can cover the time while I'm in class as well as one or two other days during the week for a total of about 16 hours per week. We're looking for someone who has previous experience working with infants and toddlers, is CPR certified, has first aid training, and strong references. Spanish speaking is preferred, but definitely not required.
