I need you to write an academic article. I need a native English speaker to help me with a research paper relevant to English linguistics. I will provide detailed instructions. I need someone who is well-versed in APA and can write the introduction part that is of around 12-13 pages as a trial for $20. If that is successful, we will proceed with the whole research paper that is of around 50-60 pages. I will provide detailed instructions for each and every paragraph of the introduction chapter. You will just need to do some minor research and write accordingly.
