Startup Idea : Flatmates for Couples

In most metro cities, the rent of properties have sky rocketed. It is very difficult to find a decent place for living alone. So there is an increasing demand to share houses with other couples. Idea is the create a web site which lists, flats for rent on shared basis. Each room can be rented out by 2 males/females or couples. The web site would handle to hassle of moving in, rent agreement, rent payment by itself.
