We have approximately 100 episodes of an old TV series together with a script as a PDF and a subtitle file as STL.
The subtitle file has errors which need to be corrected.
Timing is mostly OK, just a few words have been incorrectly interpreted.
I need experience English subtitlers to check and correct each file and return to me a corrected STL file.
You will need to be fluent in English for this task and be prepared to start immediately as we have an urgent deadline.
Each episode is 25 mins long, please supply a cost per episode.
Show me your understanding of English by pointing out the grammatical error I have made above.
