Build a Website -- 2

I need a portal like [login to view URL] with flights and hotel room upgrades, adressed to people which booked already something lower class . They can bid better room in hotel or seat in airplane which is avalaible in this same time and place/[login to view URL] main difference is bids throught web page (like on ebay), not throught mobile app like on this site. There will be an mobile app but later. Main functionality: - integration with airlines (Farelogix) and hotels API . I think that it will be 2-3 integrations. - panel for airlines and hotels: login with password, import avalaible rooms/seats - (API or manual), possibility creation of auction, import bidder's e-mail (API or manual) and mailing with invitation to them,, summary (list auctions, successfull or not , financial etc.), - panel for bidders : login, registration, user data, access to auction (not all - only invited), bids functionality, credit cards payment. - confirmation and other mails, Design will be ready to a few weeks. I don't need it. Site must be secured, resistant to attacks, ready for a few language versions. I know , not all is on application side, but code should be good written. It could be builded on framework like Zend but something like Joomla or Wordpress is unacceptable.
