Problem:

The issue here is that the user wanted pagination numbers with the format
1-12 of 2,000 results found
Click Next
13-25 of 2,000 results found
Click Next
26-37 of 2,000 results found
and so on.

Solution:

It wont be possible to have your pages labeled as 1-12 of 2,000 results found.

You can have it as 12 of 2,000 results found and this is because of the limitations of the shortcodes that will be employed to display this information.

They can only display the current results count and the total number of results. The only way i see this being possible is for you to make use of a custom shortcode to minus 12 from the current page results count.

This will involve that you pass the following shortcode into your custom shortcode and using your custom shortcode to display the final results.
