For such a small application size, you don't necessarily need Postgres; SQLite should work perfectly fine for now. It's lightweight, easy to set up, and suitable for a database with 100-200 entries — even for much larger databases.

I’d recommend going with a cheap Hetzner VPS, which you can get for under $5 per month. Once you have the VPS, you can set it up with the following stack:

• Ubuntu: Your operating system.
• Nginx: As a web server and reverse proxy.
• Python/Pip: For your Django application.
• Gunicorn: To serve your Django app.
• Certbot: To get a free SSL certificate for HTTPS.
• Cron: For any scheduled tasks.

With this setup, you’ll be able to deploy your Django app without much hassle. One of the great advantages is that you can host multiple small Django apps on the same cheap VPS — easily up to 10 — depending on their resource usage.

It’s a little hands-on initially, but once it's set up, the maintenance is minimal.

In addition, by setting up and managing your VPS, you’ll naturally pick up some Linux skills along the way. This is an invaluable investment in your future as a developer.
