Not sure, but someone that has govt regulations as one of their areas of expertiese. I'd ask Chat GPT what kind of lawyer would be best (make sure to provide as much context as possible). Also, if you have access to ChatGPT Deep Research, ask it to find textile and button manufacturers in the us that carry the type of producta you are looking for. Ask it tp provide links to their sites and whatever other info you need. You never know, it might find something you haven't yet.
