Question for NSFW pin creators:

I'm thinking of trying my hand at having some pins made. I figure I can comission an artist to do the art and pay extra to get permission to use it commercially, as I've done that for embroidered patches in the past. That should be easy. The hard part is finding a good manufacturer, from what I've heard, and I know it's really tacky to ask who you use to manufacture your pins, so I won't. I don't want to intentionally slow down your production or wait times. Instead I'll ask if you could let me know if there are any to avoid. Preferably through DM, so it doesn't hurt any feelings. Are there any that bait and switch, that sort of thing. If there are any manufacturers that want to brag about their clients, however, I'd be happy to listen. I might even finding out about sellers i haven't heard of. (I'm a new collector) if appreciate any input. Thanks in advance. (even if it's just for taking the time to read this)
