Classical Brass Quintet Arrangement Needed

I'm in need of a talented and experienced music arranger to transcribe a piece for a brass quintet based on a YouTube video. The arrangement will be used for a performance, so it needs to be engaging and suitable for live audiences.

Key Requirements:
- Create a classical-style arrangement for a brass quintet.
- The arrangement should be performance-ready.
- Ability to transcribe music from a YouTube video.

Ideal Skills:
- Proficiency in music arranging, particularly for brass instruments.
- Prior experience arranging for brass quintets.
- Strong understanding of classical music.

The arrangement should be tailored for the following instrumentation:

Flugelhorn 1
Flugelhorn 2

Tenor Horn 1
Baritone/Tenor Horn 2
Trombone 1
Tuba 1
