Hi..
I`m Peter, native Polish (from Krakow), experienced freelancer.
I did already similar works (pls check in my evaluations),
/at the moment I do more complicated task= creating PL LYRICS to kids-songs from EN sources -it`s not only "translation", but it needs to match rhythm and melody flow of song../
and I can do "your" project too ..
I use Excel too=> I know how to work with it..
Pls send your source, ask if you have any questions to clear.. and let`s go..
