Hi, finding a guide vocalist for a short demo

Hi, I need a guide vocalist for a really short demo ( app.20 sec for 2 different toplines.) There are also some dups and backing vocals. I know the schedule is tight but it must be done until tomorrow. Thanks :) p.s. there is one more 20sec short topline.

Additional info:
I'm looking for a female singer. I don't need to use your name - you can be uncredited. Check out what I uploaded. 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 need to get it done by DATE.
