Hello everyone, i am a native polish speaker, using a B2 / C1 english as well. Translating your document won't be a problem for me, i can work few hours a day, every day for you. I work for my boss 8 hours a day, from 8 am to 4 pm, then the rest of the day i can spent on working for you if you let me to. I am a very humble person, very dedicated, I will contact and discuss every issue that would occur during translation - only to provide the best service I can. You can really trust me on this, see for yourself :)
Best regards, I am looking forward to reply from you.
