Translation of a children's book, RU-EN

I'm looking for a translator:

- with experience in literary translation from Ukrainian/Russian into English

- genre: sci-fi / fantasy

- target audience: 14+ years old

- reference: Harry Potter and similar works

The work is planned to be released in the Western marketplaces of Europe and North America:

- publication of the book: printed version and e-book

- film adaptation - feature film

- computer game

- merch

Therefore, a modern, youthful, "live" translation is needed. Understandable by today's youth and also by an older audience.

Please, send me your cover letters in English. I would appreciate it.
