We are a company who develop apps and we have been developing apps for the last 3 years. We're looking for someone who is a native German Speaker to translate our apps from English

We are looking for someone to help us with translation of our application from English or Slovenian language to Italian and Spanish language in the next few days. Long term cooperation is desired. Excellent reading and writing knowledge of above languages is required. (Currently application is in Slovene and English language, so we can translate from any of them)
We need to translate website http://evinar.si/ (new version with new text) and also applications that you can see in screenshots on that page. We already have a list ready for translation (~ 10000 words currently in Slovene or English).
Work plan:
- First we will show you our application to give you a basic idea of the domain (~1h)
- You will translate from English or Slovene to Italian
- We will include translations into application and review the app together with online session (Clicking around and comparing texts and context) (-2-4 h)
