加拿大采购需求：定制街头服饰制造商，黑色连帽衫，男士连帽衫，白色羽绒服，女士夹克，女士夹克

I'm looking to place an order for medium-sized T-shirts in black, featuring a white print. The fabric should be 100% cotton. Could you provide me with the pricing details for a single T-shirt? Additionally, it would be helpful to know if there are any minimum order quantities or bulk pricing options available. I'm also curious about the production lead time and shipping costs, as these factors will influence my decision. If you have any specific design templates or customization options, please let me know. Looking forward to your prompt response!
