尼日利亚采购需求：3头绣花机，廉价绣花机，服装绣花机，电脑绣花机，电脑绣花机，电脑绣花缝纫机

I'm reaching out to explore purchasing options for a monogram embroidery digital machine with both one and four head configurations. I'm particularly interested in understanding the specifications, features, and pricing details for both models. Additionally, I'd like to know about the available accessories and necessary software for optimal performance. Could you also provide insights into lead times for delivery and any warranty or after-sales support you offer? Understanding your production capabilities and potential for customization would also be valuable. If there's any promotional material or product catalogs, please share that as well. Looking forward to your detailed response!
