I think you may hardly find day time maid who can work from 8 to 7. However, you may try 家務通 and see if they can arrange any for you! I guess the local domestic help may cause you more or less the same as the overseas one or even more expensive.
my new job OK la, I am adopting anew life here as this company size is pretty small. I feel the culture is quite different in compare with last and previous companies, as I used to work for MNC for nearly 10 years.
BTW, see you this sunday, if u still have not received my address, please PM me.
