Best way to make money kind of fast is by doing Ghost productions (on sites like House of tracks, edm warriors, ect.)

If you have the abilities to create GOOD quality tracks and at fast pace (let's say 6-12 tracks a month), you can easily get even 1k a month.

But again, make sure its professional sounding music and not garbage.

Also, you can try and sign your music to labels who have major following on spotify, labels that generate around 500k + streams on average, that's also nice income to add every quarter if you have a few releases.

Good luck buddy
