Vocal melody and harmonies needed for festival type track (songwriting not performance)

I need to come up with a kick ass vocal melody for a Festival EDM track INTRO I'm a rock/rnb vocalist that needs help writing a very good EDM vocal melody - specifically one that would fit a festival type of song for clients. My vocal influences are Jeff Buckley and Chris Cornell. JOB 1) Vocal lead melody for a verse leading up into a chorus (the drop). 2) Accompanying harmonies where appropriate - see the reference track below for details. 3) Simple backing track to sing over. Nothing crazy. Maybe some simple chords? Feel free to add whatever you think would be sufficient to send along to clients. GOAL I need a vocal line similar in range and style to this (My voice is best when I'm belting something powerful). Reference track: Reload - https://www.youtube.com/watch?v=GuAtcpFQpMw

Additional info:
The song has less than 10 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I don't need the song mastered. I'm looking to hire a top pro who's worked on hit songs, and have the budget for that. I don't have a hard deadline for this. .
