南非采购需求：门到门送货、海运、空运、铁路运输、门到门海运、国际空运

I'm looking to gather some detailed information regarding shipping options from Guangzhou to Johannesburg. Could you provide me with a breakdown of the costs involved for transporting goods, as well as any potential fees I should be aware of? Additionally, I'd appreciate it if you could share the estimated transportation times for the shipments. This will help me plan accordingly and ensure everything aligns with our delivery schedules. Thanks in advance for your help!
