I would proofread your homework, thesis, amazon ads, ebay ads, ebook or whatever else you'd need (1000w). Born and raised in Italy, always passionate about literature and writing, my handling of Italian language and grammar is proficient. I combined this passion of mine with travels, so I lived in the UK and AU (besides ES and DE) where I properly learned and practiced EN and travelled most of the world. Perfectly fluent in EN and ES, give me a chance and you'll be happy with my work! I would not only be checking the grammar but also the overall sense of the text.
I won't proofread any text that was translated by automatic tools! That would require a proper translation.
