I wanted to add a link to a page that gave more details on the membership options they were choosing from and details of what will happen after they claim their listing.
This is how I did it.
Edit geodir_claim_functions.php in /wp-content/plugins/geodir_claim_listing
Around line 1295, before
<div id="gd_claim_pkgs" class="row clearfix gd-claim-pkgs gd-chosen-outer">
<label><?php _e( 'Select Package', 'geodirclaim' );?> : <span>*</span></label>
<select name="geodir_claim_pkg" id="geodir_claim_pkg" field_type="select" class="is_required chosen_select">
<?php foreach ( $package_list as $package ) { ?>
<option value="<?php echo $package->pid; ?>"><?php echo stripslashes_deep( $package->title_desc ); ?></option>
<?php } ?>
</select>
</div>
add the following link
<div>
<h4>Available Packages</h4>
<a href="http://directory.healingsouls.com.au/claim-listing-membership-options/" class="fancybox iframe" target="_blank" rel="attachment wp-att-362">
<p>Click for more details and how your claim is processed</p>
