simple ntop project for name63

I have a very simple ntop project for name63, max budget is $30 USD, and i expect this project to be very simple. I have set up a pfsense gateway / firewall, which has netflow support, i would like you to set this up so that the ntop machine (on an ispconfig server) is logging all traffic inside, and into and from the network through the pfsense gateway, the idea is that the linux machine (ispconfig machine) will act as a ntop server and collector for the pfsense gateway machine, so the gateway machine just forwards the stats / datagrams to the collector on the ISPConfig machine. If you could set up redirection as well it would be great (but not essential) so that [login to view URL] shows the ntop information. Thanks!
