I am a native Lithuanian currently living in Lithuania, in the past, my IELTS score was 8.0.
A few years ago, I did some translation jobs for IMS health and some translation jobs on freelancing sites (50% of these are on some milestones I think).
Since I am not sure how big the actual translation is... In theory, the rate would be something like 0,03 euro per word - or you can always try offering your own price.
