Web site for real time based tracker

I'm looking for an experienced web developer to create a website for me that features real-time updates. I have a specific design in mind and need the website to be developed and launched quickly. The website should enable users to interact with a real-time based tracking, as well as enjoy a seamless user experience using their accounts to login and access the content. I'm looking for a reliable freelancer who can deliver a successful website that meets the criteria of my project.
