Here is a typical posting on Freelancer.

Does it represent a "legitimate" action by the student?

I need someone to proofread an academic dissertation of 35,000 words.
Level of English is already very good, just need to go through some details like :
1. Avoiding colloquial abbreviations.
2. Avoiding bombastic words when simple ones do.
3. Avoiding using the same word over and over again.
4. Avoiding a conversational tone.
5. Use a more academic style of writing, by using 'we' instead of 'I', for instance.- improve style and tone.
Material will be submitted in parts within the next few days. Deadline for the whole job is Wednesday 28th August.
I'm attaching the first chapter here.
KINDLY PROOF READ THE FIRST FIVE TO TEN PAGES AS A SAMPLE OF YOUR WORK
