Adding audio to sound

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.

Those who have a relevant portfolio - I will create personal tasks for voiceover of this level as a test task on freelance. 3. Trailer: https://www.youtube.com/watch?v=jFhBHgEhcgY 4.

Hello dear friends, the project is sad. While I was in Donbas, I sent my family abroad (to be safer). I came on vacation to them here. The house is not ours. Everything is clear to me there, but unfortunately, others do not want to hear clearly and say that there is only hissing. In short, remove the noise without water and strengthen the conversation if possible. Translation from German to native language.

Need to clean the sound from the surveillance cameras, 10 minutes Remove wind and any other sounds except for communication

There are 4 videos, an example is attached This is not ours, but we have something similar Ours, unlike the one in the attachment, has a very quiet alarm sound at the beginning, this volume needs to be increased Besides the alarm sound, there are also voices of people The task is to somehow increase the alarm sound without increasing the volume of the voices of people As an option - replace the alarm sound with another one (I will say which one would be better)
