Add Sub-Categories and attributes similiar to dba.dk to my site.

Hello. So i have this website called, [login to view URL] Which is a Classifieds [login to view URL] if you look at picture one, you'll see the red marked to left panel is a Search engine alike with categories. Try press as an example on "Biler" you will see it will search for only that, atm i have not added any listing so the message that it gives "No results found for your query." that's okay. as said, thats because i have not added any listing on that category. But now, please go to the website called [login to view URL] and look at the left panel, there you will see the category called "biler" again, try press on that, then you will see alot of Sub categories and attributes -look at picture 2-. This was just an example of one category that i tried to explain, The problem is, that my website does not have these sub categories and attributes, and i want that!. it is a classified website, so customers should be able to search for more detailed items and stuff. There are for sure some attributes or sub categories that i dont want, and those i will explain and tell you. HAVE in mind, that this means, that when you add these subcategories and attributes the custommer should be able to choose these when he/she ads an add in future, we will go through tests etc, and you will understand the mechanichs of the website. You should be able to talk 10/10 english, since i have wasted more than 3 weeks and alot of money on devolepers that couldn't understand the projekt properly. AND you should be able to talk with me on skype.. with a good connection, so we can really understand each other and the requirments. you will get pass to the root etc, and work online on the website. the Best and fastest and cheapest will get the projekt.
