you get trash, sell the trash and upgrade the cooldown as your first few days, or get faster
There is a ridiculous economy of selling various bits and bobs, mostly trash. There's also a lot of crafting. By the end of the first week you can have a lovely robot assistant and at least one full bitcoin frame and be working on a farm... And never sleep once. Oh and the base will be mostly if not completely clean. You'll even have enough food for random guests if you plan well. Plan well. Trust me.
