When you submit your work to us, it will be assigned to one of our editors. They will then begin proofreading your paper, checking from beginning to end for punctuation, spelling, and grammatical errors. All editing is carried out in track changes, which is a feature in Word.
We will correct badly structured sentences or grammatically incorrect sentences. However, if we come across a sentence or phrase that we feel needs further work, we will highlight this for your attention and include our suggestions as a comment in the document.
All final work will be sent back in two versions. The tracked version will show all our corrections, while the final version (or 'clean' version) will show all those changes made. Therefore, you will be in complete control over your work, and be free to accept or change back any changes you do not agree with.
This really depends on the amount of editing involved. However, as a guide:
5000 words - 1-2 days
10,000 words - 3-4 days
20,000 words - 6-8 days
