Need an ASP guestbook application

Hello friends. I am trying to make an application for guestbooks but for all members who are schools. I mean : The schools in my town sign up as members at our website with theis school's complete profile. Whenever they have visitors to their premises, they log into our website and enter the vistors details, when he arrived(date and time) and when he left(date and time). The members can see only their own records and not anyone else's records. The members should be able to query their database and find out who had visited their premises between which date/times. I wonder if there is a ready made secure application like this available. Can someone please help? Thanks very much Denis
