Around how much does it cost for scar removal through laser surgery?

I popped this one zit on my face.. and then kept picking at it. (man im such an idiot). Now its this huge mole looking scar thing. I want to get rid of it because it's tainting my beautiful face. But i'm poor as hell. How much does it cost for laser resurfacing? Or should I use Mederma or Silicone sheets, which one is better?
