How would you be able to make money (Or whatever is used as currency) in a zombie apocalypse?

Me specifically? I'm a passable military tactician (applies to big enough settlements to make human on human warfare a factor), a settlement layout designer, I possess all the knowledge to go from just your hands all the way to a steam engine (with the exception of the stone age to metal transition - I lack prospecting to find metals. Oh and I know jack about herbal medicine, though I'm able to at least produce penicillin), sewing, leatherworking, carpentry (this one I have the most experience with), game processing (from cooking to making use of all non-edible remains), crossbow production an maintenance, psychology, and lastly (though I hope I won't have to do this one), slave training.
