Need help arranging a song (not for the website)

[cashwarrior1]

I want to arrange this song as a piano duet for an upcoming piano recital (in December). I was going to arrange it myself until I realized I have no idea how to notate some things as well as the solutions I came up with I couldn't notate. I'd be very happy if someone helped out with this. Also, I was going to do a duet with my crush, so don't make the bass clefs too hard, please, thank you!

Here's what I got so far (it's not much and it's not very good/accurate).
I started out with the bass, but I can't really get it correct as the tempo and dynamics is determined by the player.
