I’m not so sure I understand how this works. How exactly would you become an ISP? Who would you need to talk to and how exactly would you make it work? As I understand, there are major players like AT&T that are pretty much the “backbone” of the internet, and you need to talk to those guys if you want to “resell” internet locally. But, I’m curious to know how much something like this would cost… and how easy would it be to, say, get fibre going in a small residential area. Every resource I found online doesn’t delve deep into how it works and the steps you would need to take to make it happen.

If you build your own actual access network, you will have to lay cables around in the neighbourhood.
To build your own virtual backbone, you buy IP range and ASN from ARIN or its sub branches. IPv4 ranges have already sold out years ago, you may need to buy them from circulation.
Then you lease backbone circuits from those backbone ISPs, those are circuits, not actual internet, what runs inside of your circuits is your own business. You can use these circuits to build your own backbone network by connecting them via routers and assign the IPs in your IP ranges to routers and devices connected to your own backbone.
The last step is connecting it to the internet backbone. Usually you are not big enough to ask for ISPs to peer with you so you have to buy IP transit links from them. These transit links connect your network to the real internet. You need to discuss route broadcast details to broadcast routing information of your IP ranges to the public internet via BGP, so routers on public internet backbone will know where to send packets destined for your IP.
