I'm not sure what you call "advanced English" but I probably can! In any case, if you want to be sure you could send me a sample of the text either here or through discord and I should be able to tell you whether it's doable or not! ^^

I was trying to be humble with my previous reply but the answer is yes. I studied English for almost a decade and took many classes on English and Spanish grammar while studying for my translation major. I have the knowledge and experience to translate any text that isn't too technical, i.e. a physics paper. I hope that answers your question ^^
