美国采购需求：门到门送货、海运、空运、铁路运输、门到门海运、国际空运

I'm reaching out regarding our plan to source bulk cement, specifically ranging from 1,000 to 10,000 tons, for import into American Samoa. We're looking to partner with a reliable supplier in China, preferably located in Qingdao or Jiangsu, who can assist us with this procurement. Could you provide detailed information on your bulk shipping rates for this volume? Additionally, any insights on lead times, payment terms, and delivery schedules would be greatly appreciated. We're eager to explore potential collaboration and look forward to your prompt response.
