You can kit all the components yourself... or make a little family fun!
It's important to QA your kits - no one wants to open a dud!
Use plates, cups, or small containers to separate your components. Then, give each of your staff a battery and show them how to assemble / test a kit.
Good kits are disassembled and go in a small ziplock bag, bad ones are retired to the rubbish bin.
Time to add a battery and set of components to each one of your packages. Root Beer Floats may be needed at this point to replenish the massive amounts of energy expended.
