Proofreading of an English book of c. 40k words

I have written a book on international law and political science. The English version will be distibuted primarily in the US.
The translation was done by DeepL and I went over it already one more time. So there should not be too much to fix in terms of grammar.
A sample is attached for reference.
I would prefer someone as a proofreader, who is familiar with legal terminology and US English.
Please feel free to reach out to me in case of questions.
