[K12OSN] internet content filtering

[Will Hatch]

After looking into content filtering a little bit, it seems to me that it is unlikely that I will have the necessary knowledge to install iptables, squidguard, and Dan's Guardian, by the time school starts.  It just seems too complicated for me at this point.  Is there a reasonably priced content filtering program that I could purchase and install via cd to my server that would get me through this year? I've seen several that either do not give pricing, or charge per machine.  Technically, I'd only be installing on ONE machine.  Any direction on this would be appreciated. Thanks! -Will
