Babysitter Needed For 1 Child In Los Angeles.

I am looking for a great babysitter for 1 child in Los Angeles. I am visiting from out of town and presenting for two days starting at 8 a.m. at the conference and would appreciate a babysitter to play and read with my daughter over the two days in the conference hall with me. We would like a babysitter who has their own car, who does not smoke, who is CPR certified and who has college degree. Thank you
