Italian translation

Hello freelancers, My firm is currently seeking for a native speaker, a translator who have a strong understanding of the Italian language to translate marriage documents from English to Italian
We need to translate this marriage document of Mr&Mrs Lorenzo Aria into Italian language. This needs to be done by a native translator a specialist, The document is 200 pages and includes some editing. It's a confidential marriage document that needs proper attention in translation.
Probably this translation is needed in the standard Italian language. So translator should be familiar with the computer operating system and most importantly
Google translating app is forbidden to carry out the process.
