Integrate GeoIP database in an openX adserver.

I am running an openx adserver and want to use geotargeting, city based for germany and country based outside germany. I already purchased the database from maxmind, so I just need somebody to integrate it properly. IMPORTANT: the interface of my openX adserver is in German. So I need somebody who is familiar with OpenX, so he can find everything he needs. When you make an offer, please let me know, if you have already worked with OpenX.
