We could sell this real estate portal, to a local estate agent. It could contain features, not seen in an existing real estate portal. I could write a sales script, to help you sell this portal.
I could code it in HTML, CSS and Javascript. This code is always run, just by using a browser, and is future-proof.
Members can submit their content, via email. This manual update, of the website, helps to ensure the quality of the website.
What would make the portal really good to use? There could be a predictable search function. This search could immediately come up, with the list of properties, without having to press the search button.
