Hello! Asking for a friend (Native Russian speaker). She wrote an article and the publisher requested it to be proofread first. It is about 4000 words in English. She is curious whether it can be done in an exchange cooperation format: she will proofread something of the same amount of words in Russian for free in exchange for her article being proofread in English by a native speaker. Please let me know if it is possible and if you would like to exchange in this format. Thank you!
