I provide detailed proofreading of spelling, punctuation, grammar, capitalization, and sentence structure, to your specifications. I am a native American English writer, but I can write/proofread to other standards (British English, etc.). At a minimum, I can find all indisputable "hard" errors (uncontested misspellings, doubled words, typos, etc.); if desired, I can edit for readability, sentence flow, and other organizational elements and make suggestions accordingly.
