Need Vocals for 1 song

I’m a Rap producer from the UK, I’m recording an Album and I need Rap Vocals on one of the tracks. The track will be inspired by the likes of Kanye West, J Dilla and DJ Premiers work so it’ll be in the style of 90s to early 2000’s. The topic of the rap is up to you just do whatever you feel works on the beat.

Additional info:
The song will be released commercially. I'm looking for a male singer. I'm looking to work with a very experienced singer. I need help writing both lyrics and a vocal melody. I don't have a hard deadline for this. I'd like to use your name as the vocalist. The song has less than 10 tracks recorded that need mixing.
