How to get second shooter gigs?

Hey everyone! I am just starting my business and would really love to have second shooter opportunities, but I don't have any photographer friends who could take me.

How could I get opportunities?

I feel like every Facebook post I come across is already flooded with comments, and I have been feeling really discouraged. I would even do it for free because I really want to learn, it just feels impossible to get my foot in the door.

Appreciate any advice!!

I'm located in Miami btw :)
