THe pix is a Hardware firewall, Easy to install if you are using the PDM (graphical configuration), using a web browser.. You'll need a professional if you have trouble configuring it for your needs, some things can only be accomplished via command prompt interface.. But most of your config can be appied via The graphical one.

Have a look at http://www.ipcop.org

IPCop turns an old PC into a harware firewall and has built in IDS

You can also add on other functions such as web content filtering.

Recommendations:
PIX firewall - put your publicallly accessable hosts on a "DMZ" interface.  You will need a minimum of (3) interfaces (trusted, untrusted, DMZ).  PIX 515 is the minimum.

Intrusion Detection - Snort for no cost and there are lots and lots of additional supporting products

   - or -

Tipping Point - Intrusion Prevention; inline intrusion prevention system

Hope this helps you!
