Need a female singer to do a creepy horror tune ( needs to be original non copyrited song as it for a horror game )

It for a game trailer 

The trailer idea atm is

Looking for someone to create a game trailer for this . The idea is my character looking for one of the tormented characters while they are hiding in a locker.. I sing creepily  ( not you) " ringa rings roses .. giggle half way through and then sing " we all fall down " and open up the locker and you head a scream and goes blank. 

Idea is the singer sings a creepy tune at start of game while a character is hiding and breathing heavily and then the singing fades and stops.. then I'm singing ringa ringa roses. Please do not do the ringa ringa in audition :)
