Configure FMS like Freedocast for Live Streaming

I have a website similar to [login to view URL] with Jwplayer. I have dedicated servers with FMS 3.5 installed to handle live streams. I am looking for an expert who can configure my servers to provide the best results to broadcasters and end users. currently i am using default ways to allow streaming to registered broadcasters. for example broadcasters broadcast using Flash Media Encoder with url like rtmp://server-ip/live and some stream name. the default settings are causing high load on CPU and very bad performance by server. i want some with experience in similar field who can configure FMS and other things that will improve site performance.
