Need a male vocal for a duet

I've finished producing/recording a track that plays to the style of an old school rap meets contemporary Pharell-esque track (for lack of a better comparison, haha). The track will play with a male verse section and chorus and potentially a female vocal hook. Looking for the male vocalist/rapper (either) part for this record. Would be helpful if you could also send a reference if you've sung in this style before. Thanks in advance! Looking forward!

Additional info:
I'm interested in working with a very experienced mixer. I'll need you to master it too if possible. I don't have a hard deadline for this. The song has somewhere between 10 and 30 tracks recorded that need mixing. I need the vocals tuned as well.
