How to create a video conference on a web-site? (streaming video coder needed)

Does anyone know how to do coding to allow for direct streaming video, so that the readers can use web cam or camcorder to talk in front of and the viewer can see that image/person...

"So I could sit at my table and talk in front of the web cam and someone else could view....? Please reply, if this seems like something you could do. I already have the outer website, I need the streaming component added and this is a starting project, so its a tight budget, but I am interested in hearing your bids for this project..
thank you
