sorry.. this item is too bulky not worth to be using air freight as it will extremely expensive then bought local

Sry i don't used sea freight. my forwarders are using dhl air freight only furthermore this is not what u est the price of purchasing from oversea.
the price is quote not only with the package size but also the weight of the item.
DHL charge according to the item chargeable weight / international shipping volumetric of the item WxHxL / handling fees / service charges & etc. BUT NOT included with our local kastam tax as well. So usually i do not recommended to combine shipping. with my others customer order and shipped back together to prevent the shipment get stuck by the kastam.
if you don't mind to paid all the extra service charges i Won't mind to purchase for you. But it's under your own personal shipment. And i can ask DHL to ship this shipment direct to your address. So if your goods/ shipment get hold by the kastam or get tax that's under yourself payment to the kastam.
