Looking for Singer/Co-Writer (Grunge/Metal/Post-Rock-ish)

My name is Alex (M,26,German) and I've been sitting on a bunch of Demos for a while and would like to release some of them as an Album/EP this year and maybe even play some shows. I play drums, guitar and bass and know how to produce and mix. However, when it comes to my own material, I have a hard time finalizing the demos and would love to have a second person there to figure out where to take the songs. Since I am not a singer, I'd also need some help coming up with the top line and lyrics.
My influences are currently: Basement, Deftones, Turnstile, Hubris, Thornhill, Silent Planet, Radiohead, ...
Here is a collection of demos you can listen to: https://drive.google.com/drive/folders/1C0qZzYArOrMYP5AyETz4Co5B2oC6pSzz?usp=sharing
