Need vocals for 1 EDM upbeat dance song

I have a song that was originally created to be a remix of Kill My Heart by Zack Martino using a stem of the original vocals from that track. However I can no longer use that stem as it was for a competition (that I didn't win haha) so I have to use a different vocal with the track. If you were to sing your own vocal to replace it, ideally something melodic, how much would it cost? I'm happy to either write the lyrics myself for you or if you have some ideas you'd like to run with then I'd be happy to hear those as well. All depends on the process and how you normally work and the cost. I've uploaded an MP3 of the track without the original vocals for you to hear. The original vocals were present during the verse sections but for the drop its purely instrumental. If you'd like me to send you a copy of the track with the original vocals to get a sense of what it was before then please let me know. Look forward to hearing from you, Gabe

Additional info:
I need all the vocals recorded (lead vocals, harmonies, stacks, ad libs). I'm looking for a female singer. I'd like to use your name as the vocalist. The song will be released commercially.
