I did a quick search, but didn't find anything about translating this is other languages. My company can handle Spanish, and we can help find other languages too.
We did linguistic QA for the last few WoW expansions, some of my guys translated Runescape, we've worked on about 40 different games over the last couple of years.
We'd like to help, but we couldn't do anything else that you folks need if our lives depended on it.

Hello Quenbranto from my knowledge we are not releasing the files to be translated because the master file goes through constant change (though things might of changed). DigitalParnoid usual suggestion for translations is for you to build a dictionary.
Heres a quote from digi "start with creating your own dictionary (based on the current Skywind content or even morrowind itself). The idea of the dictionary is that you can start translating names/dialogues/etc in a separate base and then when we give you the string files you can translate (almost) automatically based on your knowledge base."
Ofcourse things might of changed and I please don't take my word as law till someone with more knowledge on the subject comes by.
Is this still the case? (That "we are not releasing the files to be translated because the master file goes through constant change")
