What is your most effective way to fulfill and package in house?

Say I am shipping a product in a box similar to this: https://img.particlenews.com/img/id/0SCJ32_0WjddmuQ00?type=thumbnail_800x600

There's three things I am trying to figure out:

1. Box
2. Labeling/branding
3. Shipping

What would be the most cost effective way in low quantity?
