I am an Austrian student and German is my native language. My English level is almost perfect and I would be ready to translate the spreadsheet for you. BUT: Realistically, the time and budget is ridiculous. Let's take the worst case scenario: 4000 rows * x ( x = amt. of attributes [title,...]) -- let's take 3 attributes to be translated -- that would be ~ 12000 values to translate. If it takes me 1 min per row I would have to work 4000 min, which equals 66 hrs of work. My honest bid -> 400 - 600 USD.
