I work on translating videos that are in Korean to English.
I've worked for advertising companies as well, adding subtitles to their product explanation videos.
My translations depending on how lengthy the video/document is can take a day to 3 days.
If you're going for a fixed price & you need translations for a short document/video ( MIN: 1500 words / 3min video ) I will do it for $35 - 40!
