Car-SearchEngine -- 2

Hi everybody! I need a car-search-engine that is similar to [login to view URL] or [login to view URL] that searches serveral car-selling-portals on the internet and lists the findings. The main functions: 1.) Cloud-software in Ruby on Rails or PHP 2.) user administration for user accounts (charged with a monthly fee) 3.) search requests (like this: i can search BMW X5 for under 40.000€ and get an alert as soon as a car hits my requirements) 4.) realtime updates (or 1min interval update) of search requests -> AIM IS TO BE THE FIRST ONE TO CALL THE VENDOR/SELLER OF NEW ADVERTISMENTS) 5.) must support 3 portals in the beginning ([login to view URL] // [login to view URL] // [login to view URL]) 6.) multi language Full responsive design template will be delivered by professional designer! Please feel free to contact me at anytime if there are any questions
