Streaming video expert

We are looking for someone to help us diagnose and solve the problems that we are having with streaming video on our website, www.malltalent.com. Currently, our player gets stuck doing too much buffering and the playback of the videos is therefore poor. We believe that the solution is probably to move our content to a CDN, but are open to other options. We are looking for someone with experience in streaming video online and/or with implementing a CDN. Our code is written in php/smarty and we need someone to be able to spec the solution and implement it in our code. Coding can be done remotely, but if changes need to be made in the way that we are capturing/encoding video, you may need to spend some time at our location in the Palisades Mall.
