英国采购需求：运动裤、慢跑裤、慢跑服、瑜伽裤、健身裤、紧身裤

I'm reaching out on behalf of Chikondi Limited, interested in partnering with AIKA Sports Wear for our upcoming clothing line. Before moving forward, we need clarity on a few points: Do you offer sample production before orders? What's the timeline for sample delivery? Can you accommodate initial orders of 30-50 units? Additionally, we'd like to know shipping options, overall production and delivery timelines, customization capabilities, warranty details, and payment methods. Also, I faced issues uploading design images on your website. Could you provide an email or link for sharing those? Looking forward to your insights!
