美国采购需求：项圈和狗绳

I'm interested in developing some custom sets that include harnesses, collars, and leashes. I'm looking for a partner who can help me design and produce these items tailored to my specifications. Could you provide more insight on your capabilities regarding customization options, materials used, and any potential design considerations that I should keep in mind? Additionally, it would be great to understand the lead times for production and any minimum order quantities that apply. I'm eager to explore the possibilities and start the process, so any information on how we can proceed together would be appreciated!
