Audio Player Needed

Hello I am looking to create a record pool site where clients will subscribe and once a member one can download unlimited mp3 files. My biggest thing is an audio player that is simple, kinda like the one on this site. www.djcity.com

Can someone direct me to a person that is selling something like this?

Thanks

Are you creating these mp3 files yourself? If not, what source will the mp3 files come from?

My client works for Walt Disney and he is a producer and networks with many others across the world. So what I am looking for is a player or a Progress bar player. The files are loaded on his server for now.

Like this one http://www.podsnack.com/mp3-player-examples/progress-bar-players.html#2 but something where my client does have to pay 30 a month to use.
