Male Rapper vocals for one Song

I need male vocals, specifically someone who sounds like Kanye West. You would be provided lyrics and it would be approximately 3 minutes of vocals over a provided instrumental track. The key is that you sound similar to Kanye West. If you do, there is a STRONG possibility of multiple gigs.

Additional info:
I'm looking for a male singer. I will only use the vocals for demo purposes. Not for release.. I need just a featured verse recorded. I don't have a hard deadline for this. I don't need to use your name - you can be uncredited. . I work for a business with music production needs. I'm hoping to find a good singer who can work with my limited budget. The lyrics and melody are already written. I just need a singer..
