Нужно написать минусовку

There is already a ready text for a song in one project. You need to create a backing track for it and adjust the lyrics. We tried creating it through AI, the result was very terrible. I will send the text in a private message and we can continue discussing the project there.

Hello. There is a track of 2 minutes, it needs to be extended to approximately 3:45. The music is needed for a circus act. It is preferable that the performer is familiar with the concept of dramaturgy. There should be an introduction where the artist appears, moments of silence, a climax, and an ending with a point. It is desirable to maintain maximum similarity to the original, or at least the vibe and mood of the music. I don't know what the correct term is among musicians, but in our circles, we say "rewrite the music." Perhaps someone has done this before, I would be interested to hear examples. Please suggest your price for the work. Thank you all.

We are recording a song with our class teacher, we need help with autotuning and mixing, and overall making the song better. Professional intervention is not needed, just minimal adjustments to make the song sound better. We can discuss the price, we are willing to pay well because this needs to be done quickly and we understand that it won't be easy to accomplish.
