For those of you who have outsourced packing and packaging. What companies do you recommend?

Hello everyone, glad to join the community. I'm based in Delaware and recently won my first contract.

Recently I won a MIL-STD 2073 packaging bid (this will probably be my last one for a while). I didn't want to outsource it so I can learn how to do it! I got the materials needed. Now I'm stuck on the shipping/ labeling. 1) How do I print the labels to put on each individual unit (Is that via the Container ID Label, that wont allow me to click on) or is that something separate? 2) My Exterior Box is 6x6x6 and too small to attach two 4X6 labels ( Small Parcel Carrier Label and MSL Label) and a packing slip -- so I'm assuming a need a bigger box? 3) Does anyone use ZOHO for there packing slips, invoices, Sales Order, Etc. ? I/m trying to figure out how to create these things to include in the shipping and my files. 4) Lastly, if the products are shipped on the due date is that considered late or does is need to be shipped so that it can reach the destination by the DUE DATE? Sigh!!!

Denise from metro Detroit. Glad to join the group. Although my core competencies include medical & safety, looking forward to some mechanical/aerospace parts to bid on. Trying to get a better understanding of the packaging part of it for DLA? Here to learn and try to contribute. Thanks for having me.
