434333 Build an auction site

I would like to make an auction site but the object of auction will be renting, so I thought to use platform / existing components to manage and customize auctions to handle the rental of 3 - 6 - 9 - 12 months. I had in mind [login to view URL] or something with Joomla, all proposals are accepted. Consider in the estimate also the possibility to export ads on facebook, twitter and other networks. The site must give the possibility (paying) to place the ad in homepage, or at the top of its category for x days in order to give visibility. The site will be implemented in two languages: Italian and English.
