Raxitpatel,
You can already so this. I checked your site and the rates look like you are not using the USPS realtime shipping. All of your shipping is manual.
Just put the states or countries you want to have free shipping in their own individual zones. Then create new "Free Shipping" methods and link them to the zones in the Shipping charges page.
I hope this makes sense. I am really tired. I'll check back tomorrow.
