Hello, my name is Miguel. I have found your job offer about proofreading an English document and I would like to make a bid. Although I'm not a native speaker, I have about 10 years of experience working as an English proofreader. I can check and correct you document of any grammar, spelling, punctuation, typos or any other kinds of writing mistakes that your document may have. If you need to discuss anything about your project with me, we can talk on the chat.
