Osclass Classifieds Website - Some Fixing

I have a Turkish classifieds website. Some functionality not working as expected. I need a quick fix them. - Signing in with Facebook (there is a system but it has some problems) - When clicking the "Ücretsiz ilan ekle" button, there must be a page to select one the 4 classifieds categories. And the template of the category should be loaded automatically. Currently we directly go to the adding new classifieds page and when we select the category on that form, it loads the template. - There must be an autocomplete feature at the search field using [login to view URL] technology or better. - The featured ads don't show at gallery view on search results page. - For the career ads, there are some job properties on the right sidebar. They must be taken just under Job description (Açıklama)
