This project is a rough draft. If it looks like it was cobbled together who has no clue what they are doing, you would be right.
Here, I have pulled together a pack of various mods, to make the focus on trading with villagers! From the avid collector of cards, to working with a peddler to find treasures in junk, to even hiring villagers to do your work! There's a good amount of starting items, and a few little details to discover on your own.
I recommend staying away from Communicate or hiring the Wandering Trader on single-player worlds, since they have no utility without other players. I also recommend you place an Oak Sign and an Oak Card Display Case where villagers can be inspired to take on new jobs.
