What are must haves to sell?
How would you advertise?
How should I make a biz plan? What AI should I use and how? I'm retarded lol

I have a piece of land by a boat launch on a popular lake in the Midwest and would be the only bait shop on the lake. Yes it's zoned for biz.
I'm thinking one of those tiny home/barn shells but customized and finished. Around 12x40 or so. It'll be $50-75,000 + Inventory
Live bait is crazy expensive so obviously that - I live right by and have a pond I figured I'd stock and sell. And breed worms, leaches, w/e. So need live bait tanks

What else should I sell given the small space? Figured stock cheap stuff to best value mid stuff.
There's wholesalers kinda near. Buy some Alibaba shit?
I'll try to make my own shit too

Fish are Walleye, Bass, and Panfish. There's also trophy Muskie

I'm a noob and haven't been /out/ for a decade so help [spoiler:lit]or your father dies in his sleep[/spoiler:lit]
