北美地区采购需求：货运代理、无船承运人、船务代理、国际货运代理、货运代理公司、货运代理服务

I'm looking to book a container shipment for household items from Umm Qasr Port to Houston Port. I'd like to know if I can arrange this directly with you or if I need a third-party intermediary. Additionally, could you break down the total costs involved, including freight, taxes, and any port fees? Also, I'm curious about the customs clearance process at Houston and related costs for transferring the goods to a warehouse. Do you handle bookings with MSC, APL, or CMA? If so, what are the key differences in their pricing or services? Lastly, if relevant, could you explain the distinction between Kosin and Netofi in shipping?
