Sure there are writers who can do the job in one or 2 days, but that leaves the quality of the paper open to question.
You have absolutely no idea what you're talking about. There's ZERO difference in quality between projects that I book a day or two before they're due and projects that I book weeks in advance. The only difference is that the rush deadline increases the inconvenience to me and, therefore, the price. To affect the quality of my work detrimentally, a large project would have to be ordered only a few
hours before deadline, because one or two
days is plenty of time for me to write 25-50+ pages of high-quality work if I really have to and if the client is willing to pay me enough to completely rearrange my schedule (and my non-work life) to get it done. Even something substantial that I have to write in a few hours is still going to be much better than the vast majority of students in that course could produce in a week; but it could end up with some minor mistakes that I'd ordinarily catch and correct through proofreading, because if the deadline is just barely enough time to get it written, there's just no time to let the finished project sit long enough afterwards for me to do what's called a "cold" proofread.
Not all the research writers are asked to do these days are just based on pounding away on the keyboard.
With respect to this and your other comments about what you list as the "requirements of the presentation," when someone orders a piece of primary research, professional academic writers don't actually conduct research by collecting real data from real subjects. What we do is create questionnaires and other original survey instruments, but we fabricate what's called "mock data" and then analyze and discuss those mock data. This is fully explained to the customer and agreed to in advance and in almost 20 years of writing for a living, I don't think any client has ever changed his mind about ordering a primary-research project after being informed about how this is really done. The same goes for interviews: we create original interview questions and then usually write and analyze mock responses to those questions qualitatively. On only a very few occasions, I've actually conducted real interviews of a specific person by phone when that was required; but nobody in his right mind would ever think that real interviews (or real primary research of any kind) could possibly be scheduled, conducted, and then written up on one day's notice, so that just doesn't happen. In my opinion, anybody who suggests that professional academic writers actually collect real data from real subjects for primary-research projects has never really earned a living doing this.
