Custom Boxes?

I've seen some members here have some custom boxes either with name or design etched into their box. Right now my family uses custom ribbons on our boxes but the time consumption is pretty long, I think to create 100 boxes it takes us at least 1.5h which is a bit too much.The question being where are these custom runs coming from? Nashville wraps & sugar craft do some, but not the caliber or type I am looking for. I don't think we can do a batch size over 500, but some I've seen here come from very small startups like our own so I doubt everyone is affording a deep gross amount.Thoughts and referrals appreciated.-a
