Besides mere copywriting, most of the above mentioned editing services offer some combination of mechanical and “substantive” editing (see below). Moreover, as many dissertation theses exceed 10,000 words, most writing services require a customized estimate, that may be on the upper end of this price range.
In addition to copy writing (mechanical editing), many dissertation editing services offer 3-4 packages with distinct levels of “substantive editing.” Editing level offerings are often something along the lines of “basic,” “intermediate,” and “advanced” packages. Substantive editing significantly supersedes mechanical editing, including high levels of editing rigor, consistency of verbiage, maximizing impact, word choice, and academic editing. Even more rigorous processes include maximizing clarity and “flow” of the narrative, reduction or addition of words, paragraph restructuring, evaluation of figures/figure legends, and “fact checking.” However, while most dissertation editing services offer various combinations of these attributes, usually at three different price levels, it is unusual that even the most advanced service (and costly) packages include all of these, although additional services may be available “ala carte.” Taken together, these manipulations (if performed properly) greatly enhance the “readability,” and effective communication of the material, to the intended audience. This level of editing generally costs, at minimum, $100/hour, again with a turnaround of at least ten business days. Similar to mechanical editing, these services generally require customized estimates for documents exceeding 10,000 words (often with additional costs).
