Map & Compass, First Aid (TCCC) courses in Vegas?

Hey team, I’m a Vegas resident who’s recently gotten into hiking. I’d love to find some low cost courses on basic land navigation, how to read map & compass, and other similar outdoor skills.

I’m also an avid shooter and would love to find a relatively inexpensive class that covers tactical combat casualty care so that I can build out my own individual first aid kit for when I go shooting or hiking.

Any suggestions would be greatly appreciated.
