Use this excellent day care provider directory to narrow down your list according to location, hours, ages, etc. Then there is no substitute for just visiting each place in person to get a "feel" for it. I've toured the Academy at Brentwood and liked it, it's very clean although very expensive ($190/wk). Use this website for your first step:

Good luck and congratulations on your new baby!
