Making music for me

I would like to hire someone to create a music for me for my cover song. The song is “Happier Than Ever” from Billie Eilish. I want to see the (develop) slowly change in two parts from pop to kinda rock at almost the end of the song (listen to this song and you will get what i mean). If you think you could do this for me, please tell me how much you would like for this project. Thank you!

(extra tip: showing me your previous work about music or what you have created before will increase the chance of me hiring you for this project)
