Live Chatting & Broadcasting Social Community website

I need a live chatting script like BlogTV with recorded shows & a video gallery like youtube & a social community too with friends comments... , user can personal message other users... And i designed few templates for it, i want to use only my templates with little header & footer modification possiblity for users and most importantly my users should get subdomain type username like [login to view URL] .. I have the scripts of all the above but i dont know how to parse/attach them... Basically i dont like a complete clone of other websites....If you can build me whole new scripts or just attach my already owned scripts, choice is yours.. I also have little modifications to it.. My budget is 250$ - 750$ .....
