I need help in regards to where to turn when it comes to the following:

What do you have to learn//Who do you have to hire in order to do the following:

Build a website that is centered on the following model: Multiple "rooms" where people can enter and listen to 1-3 peers via live audio...essentially a website that has multiple rooms that operate as audio webcasts.....kind of like justin.tv where people can enter and watch streaming video feeds but instead it is live audio being broadcasted from fellow peers...thanks for the info.

Many forums have a place for freelancer webmasters to find work. You would be that person to offer them work. Many forums have a dedicated place for such, posting in wrong category will most likely never find you the right person.
You should make a thread describing exact detail of your project and your possible budget in the Freelance Category:

HTML, CSS, PHP, MySQL and maybe some javascript

"http://www.v7n.com/forums/looking-hire/" This forum you can post your information.
Or you can send PM the people if he is the right person you are looking for.
