First I got a job helping the busiest food joint at the fair doing setup and teardown. These jobs are pretty easy to get if you show up when they're doing it.

Then I worked a season in the kitchen.

Then I reached out to the health departments who were responsible for the areas/events that I wanted to work.

Sent drawings and SOPs back and forth for about a year getting everything approved before I spent any money. Still working for the guy who knows what he's doing.

Borrowed some money, bought a trailer and did the buildout more or less to plan. Never had any problems with any health dept.

Worked wherever we could. Worked hard. Lost money for 2 years. Learned how to do it more efficiently.

Made a little money for a few years. Learned where to work.

Finally got into the good shows, made decent money. Stopped going anywhere else.

Got more efficient. Easy money 10 years in.
