Any idea? thanks a lot!!

Enlish?

I was gonna ask that too, Enlish indeed.

I would think the quality of the shots matters more than the language of the photographer.
I would recommend taking a look at the work of the photographer, and talking to them first to see if your vision is something that they can capture for you.

If you want an american - Jason at http://www.velocity-vi.com is good.
If you want someone Chinese that can speak good English or even Enlish , SmartAnt is good - http://www.smartant.net

Disclaimer, I know both of them personally, and also host their websites.
That said, take a look at their portfolio's and give them a call and see if they're suitable for your needs.

Contact details should be on their respective sites.

If not, let me know, and I have plenty of other contacts in that field.
(I'm also a photographer, although photography is more of a hobby/creative thing for me. )

You should also give an rough indicator of cost if you repost here, as that is one of the primary concerns for finding someone who will work for you, than anything else.

Will the kids book also be in Enlish? For Enlish kids only?
What about other nationalities...
