Sitter Job in San Diego, California

Hi! I have a 20-month-old and am expecting a baby in late April (who would be needing childcare, too, starting in July). I am located in La Jolla Village and am looking for a conveniently located nannyshare- can watch in my home, in other family's home, and/or in sitter's home (if nearby). Care would be part-time and then, if working out, full-time. My son is currently in daycare but with a recent job change, the location has become difficult to manage. We value socialization so definitely want to share a nanny as well as share the burden of the cost. For 2 kids, we could manage $10 an hour so another family of 1/2 would put the pay range at 15 or 20 per hour. Serious inquiries only- must have another family to share with in area/be willing to find one. References, CPR training, and infant experience a must. Thanks!! :)
