Hello, I'm a professional music composer and I'd like to work with you, however I'm sorry to tell you that I don't currently know any singer around me to work with us on your project, I can guarantee to you high quality music with the best production quality, we can work together writing the song, making the music and everything, however as I said, we're gonna need a third party vocalist.
If you have any questions, do not hesitate to ask.
Thanks for your time!
