San,
I understand how you feel because I have 2 time experience it.
Choosing a maid,
For me, she must be married with children and not widow or divoice. Age must be around 28 to 30. (too young, scare cannot handle BB and no patience, too old scare "action" too slow(friends maid like that)) My husband said she must have some Knowledge of religious study like know to read "mukadam" (don't know how to spell). through the Biodata see the face lah if my children, husband like or not. so my this maid, I check with all my children opion also. one important one is see what experience she have that will suit to what you want.
Then Kent will help me to pick out theose suitable one and let me choose.
