Kokorogen USTs requests: who could edit UTAU well?

Hello!
I want to ask you a question regarding the kokorogen (25-string koto/singing) project I will do with the 25-string koto performer
We want to use UTAU in some songs, and now I'm asking who could do USTs well to help us?
You can say "but can you use UTAU?", no! I'm blind, and I allready mentioned that I can't
If is someone good, could he/she PM me, please? Thank you soooooooooooooooooooooooooooooooooooooooooooooooooooo much!
