Customer support ticket system

I need a website using php/mysql that would allow a customer to login and open a trouble ticket. Enter the problem -- automatically have a time and date stamp. Then, a return email will go to them telling them that we are looking over their ticket. An email will come to us telling us that a ticket is open - by whom - what the problem is - and when they posted. We then login to the admin page and we need to route the ticket to any number of our techs- via email. The tech gets the message and rectifies the problem - logs in and closes the ticket. Email goes to client telling them that the ticket is closed and when -- email goes to site admin with same info. Tracking on the admin page will track all tickets -- open/close time - time open - ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform php/mysql cgi/perl
