Navision Partner in Germany

I work for an American Corporation. We use Navision in 4 of our Europen operations. This will incease to 6 or 7 by the start of 2006. In Germany we are mostly a sales and service centre supporting 4 operational divisions. The business processes are not complicated but we do have some Navision objects (mostly reporting) that are common to all installations. We are reviewing our support arrangements and we would like to know if you can you recommend your Navision Partner to us? Thanks in advance.
