Female singer wanted for Hip-Hop/R&B song.

I have a hip-hop/r&b project where I would like to incorporate a female singer that can sing in the style of Erykah Badu. Has a smooth voice to chill a listener out and still has a nice hook to sing along to. I have the project file loaded up in a music studio. We are most likely going to re-do our verses to my beat. I will show you the idea what I have in mind.

Additional info:
I'm looking for a female singer. I need just the hook or chorus recorded. The song will be released commercially. I'd like to use your name as the vocalist. I've written lyrics, but need help writing a vocal melody. I'm hoping to find a good singer who can work with my limited budget. I need to get it done by DATE. Check out what I uploaded. I'm an independent artist not affiliated with a record label.
