Wanna be owner

Hey! I manage a sports facility that hosts a lot of kids/teen practices and tourneys. We want to buy two vending machines for our place. We have the ability to maintain and keep it stocked. Plus it’s a high traffic area with lots of people wanting drinks and snacks. I need a refrigerated one that can hold multiple types of drinks (soda, energy, protein, WATER) and a snack one. I’m finding that I can’t just pick one out that seems good and buy it. What recommendations do y’all have for both the purchasing process and the type to buy. Got about At $12k budget combined.

Ps the smart/ai ones aren’t the best option because it’s too easy for those teenage children to razz on each other and grab a quick drink while their buddies card is scanned!
