[Translation from Japanese to English ] Thank you very much for the quote for shipping. But as $435 is too expensive...

Additional info

当方は輸入業を営んでいます。今回とても大切な内容なので、契約している翻訳サービスに依頼しましたが、今一内容が見えてきませんのでこちらに依頼させていただきました。 背景は、初めての取引先から初回のサンプルを購入する場面です。 取引先メーカーはアメリカの企業ですが、工場は中国にあります。 また、アメリカにいる担当者とメールでやり取りをしています。 一度注文を出したのですが、中国から日本までの送料がとても高いので、私の知り合い（中国仕入れ業者の社長）の会社まで送ってもらって、この知り合いに日本へ送ってもらおうと思っております。
内容が伝わることが第一ですので、要約していただいて構いません。
以上宜しくお願いします。

Thank you for your estimate of the postage.
However, as $ 435 is rather high please send it this time to my Chinese partner company.
I will probably name this Chinese partner of mine as the recipient in future, too, when we kick the business into gear.
And would you be good to let this partner call directly the person in charge in your factory in CHina to talk about the details?
I would like to have them discuss about the address and the carrier.
In case there is any difficultyit for that, I would inform you the recipient's address and the carrier we want you to use.

I wait for your answer on the above.

With kindest regards,

Thank you for estimating the shipment fee.
However, $435 is expensive for me, so please send the product to the office of my partner in China this time.
Hereafter, I will request the partner in China for that when the official transaction begins.
Also, in order to consult in detail, please let me have my Chinese partner make a phone call directly to the person in charge of your factory in China.
I will have him negotiate the shipping address and the deliverer.
If you have a problem on him calling directly, I will tell you the shipping address and the deliverer I would like you to use.

I look forward to your answer to these things.
