I need 1 single Written on a already made beat.

I have already produced a beat. I have no idea how to write lyrics. You seem like a perfect fit. Thanks Nolan

Additional info:
Check out what I uploaded. I have the music and now need lyrics and vocal melody written. The vocals will be used in a commercial release. I'm not sure yet if I'd prefer ‘work for hire' or am open to sharing publishing. Can you quote for both situations please?. I'm an independent artist not affiliated with a record label.
