Does anyone have any suggestions about how I could have

Try googling something like -

"part load to Italy".

Throws up lots of options for getting quotes

Hi - in my recent investigations I have found a brilliant company in Kent that do part loads - www.bearsbys.com. I stress that I haven't actually used them yet (although I intend to), but they were recommended to me by an antiques dealer who buys a lot in Italy and gets them to ship back.  Hope this helps.
