Hi BogHog 1,
I did a similar exercise with youth groups constructing a PSK as part of a 1/2 day Basic Survival Course. The PSK items were pre-purchased and prepared, all the kids had to do was squeeze the items into the kit. We have assembled about 120 of these kits, the first 60 cost $15.00 each, the second batch was around $12.00 because I found better deals in bulk.
These basic kits were discussed/reviewed on the ETS Forum
here .
The 1/2 day Basic Survival Course teaching points were
discussed here .
Hope this can be a help to you.
Mike
