Lots and lots of money!! Seriously, it's an expensive business. You have to think about routers, switches, access servers/modems, mail servers (SMTP and POP) user database servers, RADIUS servers, failover circuits, news servers, and of course IP transit through other providers which doesn't come cheap. This is why so many small ISP's in the UK are going under.
