you don't need enough for 40 people... just a enough for a few... you can't reasonably treat more than a couple people @ a time... if ya do need to, than whatever you have in one bag will never be enough... the big things to keep a lot of are bandaids, antiseptic solution of some kind, ace bandages & irrigation water & instant cold packs & heat packs for cold weather stuff... the other big stuff you'll only need a a little bit of... OK, maybe one tourniquet, and some other trauma dressings for one or 2 people... quick clot is a grey area... not on many civilian BLS/EMT or even Paramedic/ALS protocols, so if you are not trained (it's silly I know), you could get dinged for using it believe it or not... unless your using firearms & chains saws, I'd leave the quick clot out...beisdes, quick clot is a last measure after other basic bleeding control tactics...atleast where I work it is...pm me if ya still need some info on what to stock up with...
