Hi
We've used a company called MAV( man and van) they are based in Spain and cover the Murcia region, we've used them on numerous occasions shipping things down from the UK, they charge by the cubic metre of space you require or if you require the whole van they give a set price. We wouldn't use anyone else, I can't say wether they are too expensive as I've never gone elsewhere (they were recommended to us). It may be worth you giving them a Call to get a quote. Hope this helps, good luck👍
