how to build a flashable deployment file

HI,
I have looked at various tutorials and can't seem to find one specific to what i am looking for. Apologies if it's out there and i just haven't found it.

I have a bunch (like 250) of brand new Samsung Note 3's (Canadian N900W8 build) that have stock 4.4.2. I am required to get them all configured with a specific set of apps installed and various shortcuts on the home screen along with some custom settings (APN, data limits etc). so far i have been doing this manually and it is very time consuming and tedious. If there a way to take a phone i have already configured and make a file that i can flash in odin to each of the new phones that will mirror all of the changes i need to the new phones? Or some other tool to automate the process of deploying that many devices. If anyone can point me to a tool or tutorial i would be eternally grateful :) and may manage to retain my sanity.

I haven't seen anything like this yet in my browsing, most of the tutorials i have seen are for compiling/building a full rom.

Thanks
