How to become a contractor for Apple to put new products on display at stores?

In 2020, I was in Puerto Rico on vacations and met with some family members that was sent over there to swap old phones on display in stores by the new Iphone that was released. They asked me for help and we went store by store swapping phones. I liked the experience and since then I am wondering who and how can I get in contact with someone in Apple to become an independent contractor to trip whenever Apple needs me when new products are released and need to be swapped in stores. Does anyone have the same experience or knows anything about it?
