Customise classifieds (flynax based) website

I have a valid license for the flynax classifieds software (source will be provided). I want to customise a vanilla flynax (version 4.3), with the items mentioned above, part of the HTML and CSS will be included. All the website will follow the following the following base HTML and CSS ([login to view URL]), landing page. All the adds will follow this base ([login to view URL]), we want a working booking system (the addon is included with flynax software, it may need customisation). All the function listed in the page ([login to view URL]) will have to work (Reserve now, add to want list, contact me, maps, similar items, my other listings) The login/sign up HTML/CSS must be integrated too. (see [login to view URL] login/signup) The profile page will have to follow this base (see attached file : [login to view URL]) The search page will have to follow this base (see attached file : [login to view URL]) The general site map will have to follow this plan (see attached file : [login to view URL]) with the desired functions. Many of the functions are already written in the flynax software, few should require customization The "Add an item" will have a description, a price per day or week or month and an upload photo function. Users should be able to edit their adds.
