Sorry if I'm understanding this wrong, but you said that shelters kill guinea pigs?? No, they don't. They get a guinea pig from someone who can't keep it anymore, and then keep them until someone else wants to adopt them. The guinea pigs currently in shelters aren't being killed.

If a guinea pig is usually unheard of in Greece, then perhaps your friends who want one should just get another pet, as vet care will not be at all easy to find. It seems to me that if you got the guinea pigs shipped to you and your friends, they would be more likely to die than in the shelter, because of lack of proper vet care in Greece. You said that hamsters are common in Greece? Maybe your friends could adopt one of your many hamsters! Or they could go somewhere to adopt a rabbit. It seems like it would be easier to get vet care for these animals as opposed to a creature practically unheard of in Greece.
