Esteemed Sir, I am translator with vast experience in Spanish-English translations and projects that need Spanish proofreading. I know all related about English spelling ( use of comas, punctuation marks and rest of rules of this idiom). I have translated books, web sites, journals, newspapers, medical reports, programming codes, financial statements and other type of documents in a short time (1/2 day or less even).
You can see examples of my work in the next Dropbox link:
