for running a cyber cafe you will need to get a router , maybe a outer with built in modem (adsl) then you can run more than one computer on the internet at one time .
as for price and charging , some cyber cafe use a card system to log time .
just depends on how you can keep an eye on time management .
very esay to set up, just hard keeping rack of time people are on the net for charging.
or maybe set up a couple of free computers and a free wireless conection in your cafe to pull the punters in ?????up to you
hope this helps
