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 ship 300 units of flammable gel polish from Guangzhou to East London, Eastern Cape, South Africa. Since this product falls under hazardous materials, I need a freight forwarder who has expertise in Dangerous Goods (DG) shipments. The shipment will be approximately 25 kg, and I prefer LCL sea freight, but I'm open to air freight if it's a viable option. Essential services I require include pickup from the supplier in Guangzhou, proper DG packaging and documentation, customs clearance in both China and South Africa, and door-to-door delivery to East London. I can provide the Material Safety Data Sheet (MSDS) and any additional documents if needed. Please send me a detailed quote for your services, estimated transit time, and a list of necessary documents along with any specific packaging requirements.
