What do we need to order to install Symantec Endpoint?

Hi there, We would like to install Symantec Endpoint on our network. We have under 110 clients, currently running Exchange 2007, ISA2006 and Sharepoint. We will be upgrading our server hardware and software including installing a Lync server in the next couple of months. Can someone please let me know which components I need to order for the client side and server side? Thanks, Scott
