Scott, the gent who did mine retired from the Louver business back a few years ago, but here are a few potential sources from the web.  Some of them look like they will punch holes in your metal strip (or provide one of there own) fairly reasonably.
 
Most of them punch it into mild steel, if you specify aluminum make certain its a softer "annealed" temper such as 6061-0 or perhaps 5050. If you use a harder such as 6061-T6, the louver punch will tear the metal near the end. 
 
 
 
 
 
Hope this helps

Ed and All;
I'm getting ready to cut the hot air outlet holes in my right cowl cheek.
I want to install louvered panels similar to Ed's, and wonder where you get them, and what kind of options are available?
I don't really want to buy a louver punch, but maybe?
Any help would be great, I live in the Seattle area.
Scott E
