Struggling Dj needs your help

Hello Guys ‘n Gals. I am having installed to my house broadband cable by NTL, I wish to take advantage of this by streaming live audio for a couple of hours each night from my record decks, maybe present a few of my Dj friends also. Helping viewers with IT related topics etc. Can someone tell me where I can get the relevant software to do this and if my ISP may be able to act as my server or do I need to do that myself. If this works will you all tune in, log on, and listen?
