Hey, John! It's been a while since I saw you here. I don't know how to help, but you want English sentences so that you can translate them into Korean, right? If you are okay with any English sentences, why don't you try my comment first? : ) Anyway, good to see you here.

아, 존! 오랜만이에요. 나 부축은 못에요. 하지만 너 영어 문는 그래서 한곡어 번역하있어요? 맞아요?

I think your translation was good, but I have corrected some words as below.

아, 존! 오랜만이예요. 어떻게 도와야 할 지는 모르겠어요. 그러니까 영어 문장을 누군가가 써 주면 그 걸 한국말로 번약한다는 거죠? 맞나요?
