Does anyone here have any intermediate solo pieces that I can use

I need to audition in order to progress to my schools highest level orchestra. the school offers 7 levels (first 2 are freshmen only ) and I am in the 4th level. The audition requires two 3 octave scales, an ≈1 minute solo, and an excerpt that the school will post later. I’m good with all of these except I can’t find any free viola solos. Can anyone help?? 😭🙏
