My 2nd language is English and I'm study in USA my next project I have to write my final book for PHD in International Law, I do have a lot info about but my Language not Help ! What I'm looking for some body with experniss to help me to start write my book

Talk to a professor in the English Department. There is probably a student or even an instructor who would love to get involved in a project like yours.

Let me (us) know what happens.

What you are asking for is an editor. Someone, who can review your work and make sure its grammatically correct and readable. But you should not be looking to hire someone to write for you.

I think WG's suggestion is a good one.
