Seasonal jobs that might turn permanent (Tulsa)

I am looking at seasonal jobs around Tulsa that might lead to something longer. There are 14 people counting on me, so I am trying to be careful. Hours ramp up in the coming weeks. Is it worth applying to several at once?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
