Music Composer Needed for Horror Fantasy Game

I am looking for a musician or a composer to compose a music for a horror fantasy video game. But I am encountering one problem. I do not know how to describe exactly how the music will be and I present some music from other games. I would liked if it is possible the musician to compose some small music demos to find something that will fit with my game and I like it. But no musician wants to write multiple small music demos or try to make a research to find some music score that will fit with my game. I will offer $75 for a music score that will have length 5 minutes and is loop able, seamless ending and beginning. It will be used as a music for a dungeon level for a dungeon crawler game. I will show you examples and environment images to brainstorm. But I do not know much about music to provide you in depth. If the score you will write will be so fantastic I will give you some bonus.
If you will provide me with some demos or some sample ideas, before we begin it will be very appreciated because it will be difficult to explain exact what I want.

Key Requirements:
- Ability to create a consistent musical theme throughout the game.
- Experience in composing for video games, particularly in the horror and fantasy genre.
- Skill in crafting pieces that evoke a mystical and haunting feel.

As for instruments, we'll determine the specific needs as we go along, but I would appreciate someone who is flexible and can work with a variety of sounds. A portfolio showcasing previous work in similar genres will be highly beneficial.

Some music example to see the mood I am looking for.
