Getting job while out of state

Applied to over 30 plus jobs in my field and only got one call back they need me there in person to interview so I’ll have to book a short notice flight and fly down without a promise of a job.
I’m thinking when I sign my lease and get there in person to mass apply for every job even minimum wage and call and show face. Is that a good idea just risk it coming down with no job and about 3 months on savings. I could always come down and do uber or Instacart right away. Also I’m moving to Miami area
