Desktop application & server daemon

I have an Ajax chat applications for visitors of a web site to chat with the owner of the web site, and I'd like to revamp the application. I'd like to have a server daemon to handle messages (streaming) instead of using Apache, and I'd like a chat client to install on the computer (more convenient than a browser window). I am attaching a description of my project. The Ajax part of the project is working but there would be some changes to work with the server daemon. You can have more information also on my existing system here: [login to view URL] It will include installation, bugs solving after you deliver the project. Also, I want the best development quality possible. I want a serious developer only. Thanks for your attention.
