Babysitter Needed - Full-time / Part-time

We are looking for a great occasional babysitter for 1 baby (12-month-old) closed to Irvine spectrum area. No guarantee hours, roughly 3 hours/day and 2 times per week. We would prefer a babysitter who does not smoke and who is CPR certified. Need reference with similar age baby. Baby is energetic and loves outdoor. He is at the stage of fast crawling and try to stand and move but not able to without support. No baby gate anywhere around the house so need a very attentive sitter both indoor and out. Thank you
