Need vocals for one song

What would you charge for a pretty straight forward pop/edm type arrangement …no writing involved , just ‘better’ the scratch vocal…some harmonies here and there but I can always thicken up the stacks . Look forward to hearing from you.

Additional info:
I'm an indie artist. I don't have a hard deadline for this. I will only use the vocals for demo purposes. Not for release.. The lyrics and melody are already written. I just need a singer.. I'm looking for a male singer. I need just the lead vocal recorded. . I don't need to use your name - you can be uncredited.
