I need the basic template of a real estate website that allows clients to sign-up, log-in and post adverts. I have seen similar templates at online auction sites for relatively small budgets. The only thing that I want to be different is that I want the customer to require a code to sign up, one that can be changed by the website administrators. The usual, property description, pictures, ability to search by price, type etc as normal. Don't mind how it appears.
