Just a perspective from a former writer for College Writers.
This is a legitimate site. Writers got paid on time. I worked for this site for several years. I don't any more because my current job does not allow me the time.
I wrote on topics ranging from literature to science to management.
Studio College Writers does not have resident experts in different areas of study, e.g., "fluid mechanics." A writer takes the responsibility for a paper based on his confidence of writing the paper. He or she then, whenever necessary, researches the topic (read a the book if it's a book report) and does the best he or she can.
Sometimes, with the stress of having many papers due within a short time, the quality is not as good--and I've been guilty of this. I did have a few complaints from clients; when I did, I did my best to revise and resubmit. I was accused of plagiarism twice. I defended my work and my sources and this convinced the client that none of my writing was copied or plagiarized.
To potential clients. Don't expect experts in every field of study working with College Writers.
All in all, it was very hard work as a writer.
