Cost of nanny for two children

Hey!
I have two daughters aged 4.5 and 7. How can I get a good nanny with affordable cost? Are they really passionate towards kids?
Pls answer me..

If you are considering an au pair, there are many websites with resources and information that will be useful towards your query.  A simple Google search will find them.
