Editing Checkout Pages

I am trying to modify the check out pages. The template has the option of "Free Shipping" and "In-Store Pickup" as shipping methods. We are selling a service, so there will not be any shipping charges or options. Here is a link to the site:

I was able to find the php file that would allow me to edit the title (ex. "Free Shipping") of the options, but the radial button for the free shipping is still there. Can anyone please point me in the correct direction?

Thanks for any help!

In case anyone is interested mW was kind enough to provide the answer to my question:

The Shipping Modules are located in the ADMIN -> Modules -> Shipping. Simply uninstall any module that is not useful. I created an account and I see that you've already deleted the options.

Thanks mW!
