Hi, I'm Italian and I ask you to well read this message (I'm not an agency and this is not a copy - past message).
I can accomplish your task, but, to let you understand what you are asking, the work is:
1) transcript of videos
2) translation of transcription using also the video
3) sub the video, that means timing and to do a great job also check that every subtitle stay there for the perfect amount of time
The problem is not the person, it's your budget.
A transcription work for 1 video of 10 minutes can be paid €5-10, and can be a lot of words there, last time I did it in one video of 8 minutes there were around 1000 words. A cheap translation work is 1 cent per word (in the example of 1000 words it's €10). A sub work can be €3? Anyway already €20 for 1 video of 10min, being cheap.
Contact me, I would like a collaboration (we can maybe clarify the work to do and let it be cheapier, easier and faster), and I'm cheap, but cheap doesn't mean work for free... (each video can require 3-4h to do all the tasks)
