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 looking to source electronics, specifically cellphones, with a total weight of 1kg per carton. The focus is on securing a reliable supplier who maintains high quality standards and can offer competitive pricing. It would be great if you could provide details about the models you have available, including specifications, packaging, and any minimum order quantities that apply. Also, please let me know the lead times and shipping options you can offer. If there are any certifications or warranties associated with the products, that information would be greatly appreciated as well. Looking forward to hearing back soon with your best options!
