How much does it cost ? I want to make a rap song called "Monopoly" and I was wondering if you would be able to do that for me. I just need to record it and find background music.

I have finished all of my lyrics and I just need the background music and to record my rap song "Monopoly". This would be my first rap song and I want to make it the best. I want to have some sound effects such as a cash register ringing after it is fully calculated and a coin dropping but I don't know how to do that.I want it to have popular beats , but I still want it to be unique.
