IP Multicast Expert

I need a IP Multicast expert who knows how to deploy multicast in a varied environment using what is available. If you plan to learn on the job, this is not the opportunity for you. We are on a strict timeline for deployment and you must be confident in your skills and more importantly understand IP Multicast from edge to core. You must know when to use a multicast router, multicast querier, and the details of join and leave timers. Previous experience with Crestron equipment is a huge plus.
