Collaboration with a rapper

Hey! I'm an indie singer, looking for a rapper to collaborate. I've got plenty of ideas and some lyrics ready, but I will adapt to the final idea. I really want it to be different and meaningful, developed lyrics is my first concern. Check my previous work, I did a collab before, it's called Alternative Spirits by Teresa Baleri.

Additional info:
The song has less than 10 tracks recorded that need mixing. I need the vocals tuned as well. I don't need the song mastered.
