Developing and deploying wordpress as an intranet?

I’ve convince my company to run and manage their internal portal on wordpress.

They’ve decided and commissioned me with the task of creating the theme.

I have a question with regards to deploying the portal.

They have told me install (Apache, MySQL and PHP) it on a PC and to ensure that all the pc’s in the company can access the portal.

The thing is i’ve always developed a wordpress website on my laptop (wampserver) and then uploaded it to a server e.g Media Temple.

There is a dedicated IT department in the company. I would like your guidance on what exactly do i have to ask them to install on that PC.

Do i tell them to install Apache, MySQL, PHP and phpMyAdmin?

Or do i just tell them to install WAMPserver

That pc should serve the pages to the portal visitors..

Any advised is greatly appreciated.

Thanks a zillion!
