I already made portuguese subtitles to youtube videos, translated episodes of webtoons, translated tweets of a ONG to spread the project and did the abstract in english (that was in portuguese) of some works.
I assure you I do my best to translate. I am very serious and to translate a few lines the best way I spend hours searching about the words and expressions that best correspond, when I am not sure.
I am new as a freelancer but I am willing to do the best I can and gain more experience.
