You pay for the fuel, ferry, tolls etc - and o/n accom in Campanile type B&B and return flight and I will deliver/collect your car/van/truck from England for no fee. So, would cost you no more than if you drive yourself, but saves you the time and effort.
I am retired ex truck driver/transport manager. I have done 2 similar jobs so far, 1 to Braga, near Porto and one to Kos (that was a while ago though).
This is not a business, just gives me something to do. email - michaelnathan@btinternet.com
