I am looking for someone with a Van to deliver some tobacco leaves to Belgium for me.
It'll be difficult - the limit on importation to Germany is 800 unless it's commercial transport, but that means you need an EGP or bonded goods warehouse as well as being registered and the van will need to carry an e-AD too. Most people with vans won't have any experience in transporting such goods, and the German Zoll are forever stopping vans on the PL-D border.
I know some people that offer transport services, but none of them would carry tobacco or other excisable goods.
