Classified Ad Site probably Open Source

I want to have a Classified ad Site for the UK Market. I don't want someone to go and hand write something, if they have smthing hand written then great if not something like osclass, Drupal, Joomla anyhing opn source. [login to view URL] website must include a Easy to use Control panel so that I can manage the site without any problems and either create or change listings, ad advertisements manually and interactively by paying or free customers . [login to view URL] must be proven to be bug free and proven to never crash or fail. 3. Must be able to go from Free to paid ads with the click of a button in control panel Things i would like to have but might not allbe possible (let me know what is availabe) Facebook Like for all ads Twitter/tweet on all ads googlemaps vouher/code system - i can use to entice people in with vouchers for free/cheap posting in paid ads the ability to have the poster have telephone number or email adress (hidden) or both Images for all categories i-e image of car for motoring etc carousel to show latest ads or f desired latest paid featured ads To bid on tis project i would prefer if you could show me a classfied ad site you have already made or a link to a site you would think it ould look like or at the least a link to the platform/platforms you sugest our goingto use Looking forward to seeing what's out there that I can use..
