Hi there!
I am czech native speaker and translator and I would like to get in touch with you about this project.
Among other projects I am familiar with kids show as well as I have translated more than 600 pages long script for Czech TV - Noddy (English with Noddy).
I also did some voice overs during my freelance career but most of it was just short stock news and online dictionaries. Nevertheless I have many friends with home studios (as an amateur musician and co-owner of the music club in my city), therefore I can get in touch with them to either use the studio for myslef, or let someone else take care of narration.
So this is my offer. I myself can translate the script and produce the voiceover (also implement it to the video or even upload it on youtube - my main field is video editing haha ;-)).
Look like real fun and project I would like to work on, but we would need to have conversation about details, lenght, regularity and of course about money as well ;--)
look forward to get in touch!
David
