157148 Transportation site

There's this transportation website that I own, which still needs a booking engine. Basically I want a system that lets website visitors select their type of transportation, print a receipt and option to pay online or when getting down here at the counter (with their printing). It needs 2 databases: one for individuals (who will be booking everything on their own), and another for the local travel agencies who make these are bookings for their customers (got it?), each one separated from the other. The options for transportation are: standard or vip, sedan or luxury car or van and its combinations. Please make questions as many as you want, thank you.
