How did you learn about self hosting nextcloud?
I used this guide: https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md
I also had the help of a webdev friend of mine, that taught me the basics of how to setup and use Docker.
May I ask what’s the pricetag for a vps for nextcloud?
I hired my VPS for around $200 a year (after comverting from Brazilian Reais to American Dollars). It gives me a VPS with 2 vcores, 2GB RAM and 40 GB SSD. There are many VPS providers that can offer you somthing with similar specs and and prices, like Hostinger, AWS and the likes. (Depending on where you live, you may actually find much better prices)
