Need some song lyrics

I'm currently in the process of working on a rap song, I've got the beat and now some lyrics is all i need to truly finish the song, something maybe along the lines of that of travis scott or kendrick lamar

Additional info:
. I need a song written from scratch - lyrics, music, and vocal melody. 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 indie artist.
