Hello there!
I'm a bilingual Canadian, so I speak, write and read French & English. I believe I can be the best candidate to help you as I have grown up watching and translating videos throughout school. I also work as a Part-time French tutor, so I am diligient in working and getting tasks done on time.
When it comes to video translations, I am thorough and double check all my work. I would not be using any translation software, all translations would be done by hand.
I believe 3 days would be enough for me, but this can be changed depended on the urgency of this project, how many videos and how long it is.
All in all, I would be working along side with you, so any questions, concerns would be addressed right away.
Hope to hear from you soon.
