Setting up a FiveM server from scratch? Creative base, mobile, and other scripts

Hey, I’ve got a bunch of questions. I’ve always really liked playing GTA RP. I’ve already been an admin on several servers, did support, fixed some scripts, but nothing too complicated.

Today I’d like to know how I can have my own FiveM server from scratch. I want to have my own framework, make my own scripts, my own phone.

What would be fundamental at the start is having Spotify (for VIPs), a phone, a reward system for hours played, etc.

My plan to do all of this alone, even being dumb, is to subscribe to some AI plan focused on programming. What do you think about Claude, for example?

Another question is: can I make a website where people can subscribe to VIP automatically? Where would I host this site? How does that work?

Something I really want is to grab some Creative base out there with few bugs and fix everything. Put in my own little things without having to take anything from anyone.

How can I start to have all of this?
