Symantec Endpoint Protection 11.0 help

Anyone use this product? I have 25 computers & 3 servers(XP Pro, 1 Vista, 1 Server 2000 & 2 Server 2003). I looked at Symantec's online courses and they wanted $3500 and 5 days for just a class on installation!

I am looking for the quickest way to get all 25 computers protected. Their web based management tool is not very intuitive.

Mahalo,

Don
