AWS IOT, build a production line tracking system

I am in need of a production line tracking system that can be connected to my AWS IOT service. Specifically, I am looking for a tracking system that can be used to track production. I do not own any hardware yet, so I'm looking for someone who can provide recommendations on which systems to purchase. This system will be used on a small-scale production line, with the goal of producing less than 50 units per day. I'm looking for a freelancer who has experience working with AWS IOT services and building production line tracking systems. If this sound like something you have the ability to do, I would love to hear back from you!
