Sounds like a classical lan-party setup. I've done this but with 4500 
ports.

People do this with cheap switches from dlink, zyxel, linksys etc.

Centrally placed cisco 6500 (borrowed or rented) or equivalent with a lot 
of copper ports, single CAT5 from that to whereever fan-out is needed and 
place cheap 24 port switch there. Do management on one vlan, do /26 for 
the participants on another. Don't bother with DHCP protection and other 
stuff in the fanout switches, they'll only break the other 23 participants 
and it's fairly easy to faultfind.

So, in short, get cheap simple fan-out switch, do intelligence 
centrally.
