Need 250 page book translated--many languages

I will need 250 page book translated this fall and am getting
price quotes now. I am looking for pretty much any language,
but particularly English into Chinese, Korean, Thai, Japanese,
Arabic (modern standard), Bahasa Indonesian, Russian,
German, French, Spanish, Portuguese, Italian, Hindi, Polish,
Slovenian, Slovak, Bengali, Telugu, Marathi, Tamil.

Please provide a rough estimate as to how many pages you
typically translate per hour when you apply. Thanks.
