Cars & Auto market classifieds ads portal

I need to customize or develop one website for classifieds related whit cars and automotive sales. The domain is [login to view URL] and it ad a osclass script installed, but i´m open to all suggestions. Some features that i need in this ads portal is: -Features ads possibility -Ads banners for pay publicity -Paid and free ads posting -newsletters possibility -Social network integration -Automatic post of ad in facebook page -Helpdesk support for members -Ads reports Basically i need something like OLX or eBay but just for automotive ads I need some one who i can talk with, and together share ideas and opinions. This is a web site for a facebook group to ads, and the major idea is to get out of facebook and start a website for the ads. Any question please contact me.
