Your www and none www version of site work, only one should work. You can add about 3 lines in htaccess and you're set. Other than that, it sure seems like a good classifieds.
Not a bad start, I would suggest an overhaul of your logo - its just a litle too big and in your face. Everything else is minimalistic and colours are great. Also, I would suggest holding off on any more monetization ads untill you are getting more hits and ads.
Your site is loading fast and i would say color scheme used by you is a good too, i like the way you have arranged the contents
