Proofreaders read manuscripts before they are typeset to find and correct mistakes; they read through typescripts to detect and highlight typographical or grammatical error. ... Their work description also entails verifying accuracy of page numbers, headings, and captions, as well as consistency of spelling and grammar. Proofreaders do exactly what their job title suggests: they proofread materials for spelling, grammar, punctuation, syntax, usage, consistency, and brand voice. Proofreaders review and markup written work, such as marketing materials (brochures and flyers) and internal documents. And that pretty much what i will be offerings as a proofreader.
