Childcare Needed - Full-time / Part-time

Hi! Im looking for an occasional babysitter to care for my two children, ages 2 and 5, in our home in Haines City, Florida. I would mainly need help for a few hours occasionally, including some evenings or weekends. Could you please let me know your availability, hourly rate for two children, experience with toddlers and preschoolers, and whether you have current CPR/First Aid certification and references from previous families? Thank you! I look forward to hearing from you.
