You need to find out the writer who is responsible for your assignment. You have to ascertain he has the relevant knowledge that pertains to what you are dealing with in the assignment. Most of the academic writers from online writing companies should have Ph.D. and Master’s degree to ensure adequate knowledge and experience in your area of interest.
As long as you are a student, you are probably on a budget and can’t afford a costly essay. But still don’t choose the cheapest one, since it definitely doesn’t provide the highest quality, especially if the essay is promised to be done in the short term. At this point, it is likely to be plagiarized. Though there can be discounts for loyal customers which are a common thing.
Stay away from the sites that offer ‘best free essays.’ When a custom essay service offers a free essay that is cheap in few hours, chances of plagiarism are very high. They might be using one essay that they are sending their customers. Once you submit such an essay, the software that the professors are using nowadays will easily detect it.
Some of those sites employ non-native speakers and writers without university degrees and that might impact on the quality of their works. To avoid this, read as much custom reviews as possible. You can also check the requirements for applying on the service as a freelance writer.
Remember that you have enlisted their services. In other words, they are working for you. Their work is an investment in which you have put money, and you deserve good returns. They should give you a free title page, formatting, outline, and bibliography.
