Ayi/Nanny Required (Shanghai)

Hi,
We are planning to move in with a 6 month old from India to Shanghai. My wife will need to join the job immediately too.
How difficult is it to get 24/7 live-in Nanny over here?
What prices should we expect to pay-up for an English-speaking Nanny?
Are there any recommended day-cares for Protected content olds ?

Thanks for all your responses.
