need to carry on a project to create a web platform to promote real estate sales announcements (similar to www.casa.it, www.immobiliare.it).
the project aims to create a fully functional platform for differentiated groups of users who can insert announcements by paying a fee or a subscription.
main process: users input data, the system gives output using selected criteria (location, type of property, price, etc...)
must allow to differentiate groups of users and to give different permissions / views to them.
the platform must be scalable, can be created using CMS open source or proprietary.
the platform includes also a payment gateway to pay insertion of announcements.
