1 written song

Hello I have a concept for the song. I would like to colab and help write with you. I need a fire melody and slick lyrics to make this song pop as I’m wanting to use this as my Albums single before I drop it. I am looking for someone who can provide me with a reference track or Demo so that I know how to sing the lyrics in the melody correctly. I’m trying to incorporate as much vocal expression and powerful vocals to make my audience feel something ! Check me out on Instagram @YesitsMarche for my latest content I have out so you can get a feel for my voice sound and vocal range. I’m also on all music streaming platforms under the name Marchè Le’Shun. Look forward to working with you.

Additional info:
Check out what I uploaded. The vocals will be used in a commercial release. I'm not sure yet if I'd prefer ‘work for hire' or am open to sharing publishing. Can you quote for both situations please?. I'm an independent artist not affiliated with a record label. I have lyrics written but need music and a vocal melody.
