Change FREE listing to PAID

I really want to have 3 listings options - Free, Standard and Premium - I posted here and here on this.

In the meantime, I'd like to change FREE to PAID. The user dashboard has a tickbox for FREE and so does the PAYMENT box they see - how do I change the text for these boxes so they do not see FREE anywhere? Thanks

 

For this Go to the
Geocraft settings > Payment settings > Free payment package
And add your text there.

 

Thanks Nitesh - I mean when I edit a listing - here.

 

Ok, It's a admin area, No user can enter there.
If you want to change it
Go to the
geocrafttheme\library\text_domains\ metabox_path.php
and edit line number 33 and 34.
