Research paper

I have an applied linguistics assignment. I have to write a research paper about a language related problem, causes and solutions. The problem i chose is about second language learning, which is why is it that most of English learners have phonetic problems when it comes to producing the correct sounds in English like (p) and (ch) (specially Arab learners) the paper should be at least 7 pages long, including the abstract, thesis statement and the cover page. Do you think you can do it? And if yes, how much will it cost me?
