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.
Every person has a writing style that most professors are able to tell because they have marked your work for long. As such, the writer that you settle for must be able to match the essay with your writing style.
Of course, the nice design of a website is not the most significant thing, but if order button and contact information are hardly visible, you’d probably like to choose another service. The process of placing orders should be as easy as ABC in their own interests. In addition, also there should be a plain and clear price calculator and free samples of works available.
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.
Ensure that there is constant communication between you and the custom essay writer. If they have live chats or instant messaging, this is ideal. However, check upfront to confirm if this level of communication is possible.
