changing "apply now" text to a button

I am trying to change the “apply now” text on the job listings page.

I am trying to remove the previous <td>, and change the <td> that holds the application link to colspan=”2″.

I am also trying to change the text to a button I created.

Sounds simple, right? UGH!

I have changed the following:

In setup.php, I have found every instance of [job_apply_link], and changed the Apply Now text to a link to my image (leaving the hyperlink shortcode)

On line 125 of setup.php, I changed the variable $applynowtext to reflect the link to the image instead of the simple text (using the appropriate single quotes and escape characters)

Having done this, I still get the simple text link saying “Apply Now” at the bottom of each listed job.

I can’t find any other instance of “Apply Now” in any of the plugin’s files – so where is it coming from? Is it something in the database?

How can I change this? The plain text apply now link is really boring and I need to change it to a graphical button.

Jobs can be seen @ http://wp.waynereaves.com/jobs/. The only jobs on there are test positions as we are working on the entire site right now, so nothing is really “live”

Any help would be greatly appreciated!
