I am on a Minecraft Java server that supports bedrock which I am playing on. I would like to connect some of my farms (crop farms, cobblestone farm, melon and pumpkin farms and several others) - to the main market area of the server around 7500 blocks away. I would have use hoppers but hopper are extremely expensive and only available at spawn and a limited amount of them. What would be the best way to transport the items without them despawning with a small amount of hoppers. 'Best' being least hoppers, cheapest resource wise, fastest and can transport a lot of items without any of them despawning.
Edit:
I don't have any shulkerboxes but could potential get some, I was thinking maybe minecart but I don't know what happens if they enter a unloaded chunk or water flow but that would despawn. Like an alternative to hoppers. The farms will also be creating more items to transport constantly so a way to transport the items without travelling long distances through any method (even through ender pearl stasis chamber) as I will have to do this repetitively when stock is depleted. I don't mind travelling that distance every now and again to load the chunk that the items will be travelling across as it does not require shulkerboxes which are hard to come by on the server.
