Organization can come in the form of ziploc bags such as Nursemike is using. The bulk kit I referred to is essentially a few gallon ziploc bags inside a small cooler in which I received some food stuff (sausage mustard yada yada yada) for Christmas years back. For more organization than that then you probably already have the best solution. For that I really like the AMK FAK soft cases. They hold up well, but they are not cheap to buy retail.

That said, I wonder if one of AMK's custom kit would be cost effective. You might want to call them and see if they can help with this project. I wonder how many bags you'd need to order to get a significant break on price?? They're in business to make $$ but they may be able to assist -- maybe not.
