it's not lazyness, it's just about the costs
I mailed and phoned around some bit, but all the large professional firms, were too expensive and too much of an hassle
Gyruss tip about Dascher was quite good, but you have to pack your cabinet on a pallet. Otherwise they wont transport it. Then someone advised me to look around on Marktplaats, and there I found a pretty cheap (cheaper than renting a van in this case) called HubHub. A company specialized in transporting large objects bought at online and offline auctions.
so far so good, they communicate pretty fast and clearly, but we have to wait and see if they transport in a decent matter.
