Short answer: Thesis editing cost depends heavily on total word count, language quality, formatting rules, reference style, tables and figures, and deadline. A full thesis should normally be scoped from the actual document rather than priced from a generic package alone.
Universities often have detailed thesis formatting rules, so provide the handbook or template if formatting is required. Also say whether you need language editing only, structural comments, reference checking, or help preparing journal articles from the thesis.
For large theses, clarify whether the provider will work chapter by chapter and whether the quote includes a final consistency pass across terminology, headings, abbreviations, tables, and references.
Academic editing should improve presentation without changing the author’s research findings or falsely claiming authorship.
