I would recommend that you should register on AuthorAID as a mentee and send a request to one of the mentors to do the English proof reading of your manuscript

Other option can be getting help of a professional service, but it might cost you hundreds of USD
Academic language and style editing/proofreading is a skill that is attained through professional training, and not by being a native speaker. Therefore, you should look for someone with expertise in language refining and style tweaking. If it happens you find an English-native speaker with expertise in academic language and style editing/proofreading, you could consider it a plus. You might go through Hyland's (2016) article for insights into the negatives of native vs nonnative polarization in academic writing.

I agree with Mr Alotumi. Ms Boudia, you actually need expert guidance on academic writing from an academician or author who frequently conduct research, writes articles and publishes in the same field of study as yours. It is not just basic correction of grammatical errors or sentence structure problems. The whole rhetoric as a well must be sound and meet the required or preferred styles of the field.
(1) what is your timeline? (2) what is your topic? (3) is your study qualitative or quantitative? If you are not in a time crunch, I may be able to help you.
