Hi! I'd love to work on this project! I actually am working on a 3d music-based psychological horror game as well and have a lot of experience working with steam dimensions. I specialize in horror work so check out my artstation!
I'll add some of my work to hopefully catch your attention but feel free to browse my portfolio:

My game: https://store.steampowered.com/app/4687550/The_Audition/
My rate would be $17 an hour and the big layered pieces may take up to 10 hours.
