Music Production

I am doing a cover of this pop rock song in a much slow and softer version. I only have the melody and tempo with some piano chords. I am looking for someone to develop the music and track further add more to it maybe some strings or so to dramatize it as the original but in the flow I am going with.

This is the link to the original song:

I have attached a demo of my cover version of the song.

My budget is a little tight but open to discuss if needed.

Thanks, AT
