521458 Social Networking Website w/ Mobile music player

I want a social networking site that is a mix of facebook and mocospace. If it'll be cost-efficient for me, then I can buy/lease an open-source social networking script. I already found one that has the best features and it's already mobile-friendly. So I'll need someone who can add on custom ideas that I have for the website. When musicians upload music, I want users to be able to stream/download the songs to their phones when they're using their cell phone. So I need a mobile music player. If an user doesn't have a newer model phone to stream songs, I want them to be able to download the songs to their phone. Also, I would also like my forum rooms to allow users to upload audio files from their computer or mobile device. So audio files compatibility should be (mp3 and qcp {audio recorded on their phones} ). If you can allow users to embed videos within forum thread as well, that will be cool. If not, it's no big deal but I saw a different social networking script that could do it. I can't afford to buy both. My budget is small, so please keep that in mind. If you're expensive, don't know how to customize my sites by adding my new features, then please don't place a bid. REMEMBER, HAVING A MOBILE-FRIENDLY MUSIC PLAYER (to stream/download songs directly from mobile devices) is the most important part to me.
