Greetings. My name is Jeremy Trammell and I represent a group of developers and designers in Portland, Oregon, in the U.S. We have extensive experience with Javascript, and the node.js environment, and would be happy to assist you with your project. It's not entirely clear to me what you want done, though. Are you looking for us to develop a complete start to finish chess tournament website for you where the players register and play the game directly through the website, or are you just looking for a node.js server which validates moves sent to it from an external source?
