Desk.com & Joomla Integration

I need a plugin or script that would integrate [login to view URL] with Joomla v.2.5 CMS. There is a documentation available for this by the [login to view URL] support here: [login to view URL] Please read all this and let me know you can do it. There is no need to have access to my websites. You can test it with any Joomla installation to know it works. Do not forget to post both the cost and duration required.
