There are plenty places to apply, but the pay for a range officer, sales person, etc. is generally going to be tough to support a family on. Smithing would be a lot better in the pay department, but limited on places to work. If he has the ability to open his own gunsmith shop, potential income would be a lot higher once he got established (assuming he does good work and has an extensive knowledge base). Good smiths are like good mechanics, when the word spreads from people done right, they get busy and stay that way. He could check with Frisco Gun Club in Frisco (Dallas area). In the Houston area, there's American Shooting Centers, Carter's Country, Memorial Shooting Center, Athena Gun Club, Collector's Firearms, G2G Gun Range, Radical Firearms (they build and sell AR rifles, I know the owner), to name just a few. In College Station, there's Champion Firearms. He could also check with various Law enforcement agencies to see if there is an opening for a smith/armorer. Hope this helps for a start.
