title: Help with CMS PHP/MySQL project for managing jobs/tickets?
body: <p>I have experience in php but not with large scale projects.
  i am looking for a sample CMS PHP(preferably using the LAMP stack) for managing tickets, to learn from. Here are the functionalists I want:</p>
  
  <ol>
  <li>Login (with security)</li>
  <li>Users (designers,supervisors, and clients) can login and upload/review/download jobs.</li>
  <li>Clients upload jobs with files and description</li>
  <li>Supervisors assign jobs to designers</li>
  <li>Designers download jobs, and upload them when done</li>
  <li>Clients then download finished jobs</li>
  </ol>
  
  <p>Any help will be useful. Links, guidelines, projects, articles, tutorials, or books</p>
