Publicly shared internet access

I have been approached by a local hotel that wants to offer internet access to its guests. They are not planning at present to charge for the service but if the market supports it maybe they will.

Does anybody know of any good packages that will help them manage the bandwidth and (if they choose to go down that route) the billing.

I have pointed out the potential pitfalls of the service in terms of supply and demand and their lack of on-site support staff but they would still ike to look into it further. If there is a way to simplify the management of the resources they will probably farm the support out but if the management is too complicated they will probably end up shelving it for another 12 months.

All help would be appreciated.
