I need a podcast edited

I need someone to edit a podcast I have created with a friend, as well as compose a music piece to accompany it. There are many things I require:

1: I need you to clear up any extra sounds
2: I need you to enhance our voices so that they are clearer
3: I need you to slightly change the pitch of our voices in certain parts of the podcast
4: I need you to compose a music piece to accompany the podcast
