No Readymade scripts plz. I need a script for car-pooling, where in people who would want to share their cars out and people who would want to look for people who would want to share cars. The entire search parameters are based on the city, address from and address to, based on type of cars, price. Also peopole who would want to share their cars will be registered for free intially, but our admin system should have the capability of adding the paid membership module on click. Also need the mass mailing, reports, shoutbox where people can request perticular route, also the billing system. Auto email reminders for new cars added in their routes. Mass mailing to all the members. Ad banner management. Designing will be provided by us.
