Tutorial on how to hire your own sims you made, to work in your Restaurant

Gah! This is not completely working for me to get the chef I want. Only a few of my sims ( not in world) show up to be hired and I've hired my waitress and host out of them but the one I want for chef is not showing up!

I've deleted every townie not in world to get him to show up but the game keeps generating new townies that show up in the chef spot. What do I do?
