Phew that's a lot of tickets... don't quite understand what you want here but you could try emailing these guys after you've looked at their website:

Thank you for taking our module into consideration, Make Portal.

I am not very sure of what are the needs of this thread author, but what I can say is that our module support tickets entering and tracking, as well as customizable contracts that set a cap to the Tickets that can be entered by a Contact or by a Company.

You could download our demo or free version from www.oldturtle.net, and see if it suits for your needs by playing around with it.

Best regards.
