I need help in writing the Lit. Review and Methodology Chapters

The study is under the field of Applied Linguistics. It is a social study, and it is about the Speech Act of Request between native speakers of English and non-native speakers. Now, I need help in (1) editing the Lit. Review according to the feedback written there (you may need to add about 3000 words), and (2) Methodology chapter of about 5000 words (writing from scratch). Thanks
