Pickup and Deliver documents to the DUO (Dienst Uitvoering Onderwijs)

I need a responsible person (living in Netherlands) who is able to receive a post with some documents on his/her home address and deliver it to the service desk of DUO (Dienst Uitvoering Onderwijs) - Address: Kempkensberg 12, 9722 TB, Groningen. In DUO these documents are needed to be legalized on the service desk. After DUO documents are needed to be legalized with apostile at Groningen District Court (Guyotplein 1) and afterwards send it back to Spain by "[login to view URL]". All costs (travel and post) will be covered.
