Jerry,
Your best bet is to put a kit together yourself for your specific needs. Most of the commercial kits are great but you end up paying for lots of stuff you don't need. There is actually a great thread about this in the Mil/LE section and I'll link it at the bottom of my post for you.
Basically all you need is shit to control/stop bleeding and some airway management tools. We all have the same, small molle pouch attached to the same location on our tac vest. That way everyone knows where to find it in case of an emergency.
As far as contents goes:
QuikClot but the Combat Gauze variety
Tagaderms (large)
Asherman Chest seals
A large trauma dressing
C.A.T. Tourniquet
Basic OPA and NPA
Gloves and shears
Here is that thread from before that you might find interesting.
