Hahaha, I don't know a word of Korean. I do translate from Japanese, but all I do in webtoons is edition, so no need to call me "sunbae".
And sure, the offer will be up when you feel more confident. Death Toll has recently revived our webtoon section, so we're trying to start new projects, and that will require translators. When you feel it's time, be sure to get in touch.
As for edition quality, even if you don't want to worry about that, you'll improve naturally. And you chose a great series for that, the art is simple and there are only 17 chapters out. When you catch up, you'll have time to improve between one chapter and the next.
Cheers!
