I need to send a drum kit from CM to Hua Hin, what are my options ?

I am not going with it, just sending it.

Thanks in advance.

There's a nationwide transport company called Nim See Seng or something like that. Maybe they can help you. Will it be packed in protective cases?

No, I am hoping the transporter will do the packaging.

I rang Nim See (well the wife did), they charge 500 Baht per item which is good info for anyone with a large item but they asked how many pieces and I think they were not sure what a drum kit was and it comprises 5 drums , 2 cymbals, a stool and all the stands so turned out a little bit expensive.
