加纳采购需求：男士T恤、吊带背心、卫衣、连帽衫、棒球夹克、裤子

I'm starting a T-shirt line and looking for high-quality plain round-neck options. Could you share details on the colors and sizes available? Also, I'd like to know the material types, pricing per piece including your MOQ, and any bulk order discounts. Additionally, please provide info on shipping options to Ghana and available payment methods. How long does production take after payment? Lastly, is there a chance for customization or branding in future orders? Thanks!
