Translation to Dutch (from english)

We need our software translated to dutch. Its two excel spreadsheets with english, swedish, spanish, portugese and italian in each column. First part of it is already checked and OK, the rest is roughly translated with google translate. Your job will be to go though and correct the parts that are wrong. Anything unclear you can mark in red and the terminiogy that belongs to our speciality (medical field) you can just leave and a expert in that field will just look at those things later. So, really, anyone from the Netherlands, or anyone who have dutch herritage can do this. For the other people doing to the other languages, it has taken between 5 and 10 hours (and never more than 10 hours).
