Making the site more sales oriented eg a. Putting our phone number in large font in the top right corner of every page. b. Placing a prominent link or form for booking a consultation below the phone number (eg see the Medibank website), leading to a landing page, in turn leading to a secure payment facility for the initial consultation fee. c. Creating a sales page for our book, with secure payment facilities. d. We will add headlines, images, links etc. 3. Making it easy for us to edit the website ourselves. We would need a WYSIWYG interface. It should be easy to add 3rd party apps/plug-ins. Our understanding is that CMFs such as Drupal and Joomla are most suitable , but suggestions are welcome. Note this is an outline. The Winning bidder will be given a detailed brief. Please describe how you intend to achieve the objectives set out above.
