Hello there,
I'm a native Dutch speaker and ESL teacher, with over ten years of experience in translation (Dutch and English being the relevant languages in this case).
I'm a fast worker and will have enough time the coming days, so even if the videos arrive last minute, I will be able to transcribe them by February 2nd end of the day. Regarding the translation of the questionnaire, I might have traveled on Monday 28th (a ten hour bus ride in Uganda) but I could postpone the trip which means I'll be available the entire day.
Technical language shouldn't be an issue, I have previously translated academic articles with no link whats however to my field (I mean, memetics, neuroscience) but I always conduct thorough research to get familiar with argon and terminology. Therefore I prefer being paid per word or per project instead of per hour, because my perfectionism shouldn't be paid by anyone else but me ;-)
Happy almost weekend!
Karin
