-You would first have to make a new .php file.
-Name it something like footer2.php
-On the page you want to have that footer, use this code <?php include(TEMPLATEPATH."/footer2.php");?>
instead of <?php get_footer(); ?>
-Just copy the EXACT content of the footer.php to the footer2.php file and edit JUST THE WORDS! Don’t edit any div classes, tables, etc. or it will throw off the entire layout.
That is the only way I can think of…to my knowledge, there is no plugin that will allow you to have different footers.
