hi i been looking through the internet and i can not find someone who make custom packing for a clothing line im trying to start up please help
Any screen printer should be able to do a printed box for you, but it is expensive, bulky, costs more to ship your products out. They will also charge you per color so most people that this only get 1 color.
Other options that are cheaper are to get stickers made and just put it on the box or envelope.
Also you could make your own stamp. Check out this video
Unless you have a high priced premium product I would skip boxes. I think envelopes are a more cost effective way to go.
