Build a Classified Website - repost

Hi I need a classifieds website, where people can post their own classified in all fields possible. I know there are a great many CMS for this purpose out there, but i couldn't find anything that will give me layered navigation and filtering such as it is done here: [login to view URL] Basically I need to build a site very similar to this, [login to view URL], and [login to view URL] Also, a way to import classifieds in the CMS would be necessary, preferably with csv files, or API. i have the design ready. It is flexibile, dosn't necessarlity has to look like this. I have attached a list of things that needs to be included in the functionality of the site, and an image, about how it should look like. Again, i'm open and flexible, so please, don't be afraid to bid.
