Exclude Admin from User Profile Pages

I need to exclude the admin or show on the authors of the site.
Help?
Here’s my code:

<?php get_header(); ?>
<div id="inside-content">

<?php if(have_posts()) : while(have_posts()) : the_post(); ?>
<h2 id="inside-h2" class="chunk orange"><?php the_title(); ?></h2>
<?php the_content(); ?>
<?php endwhile; endif; ?>

<div id="ap-content">
<?php
// Get the authors from the database ordered by user nicename
global $wpdb;
$query = "SELECT ID, user_nicename from $wpdb->users ORDER BY user_nicename";
$author_ids = $wpdb->get_results($query);
// Loop through each author
foreach($author_ids as $author) :
// Get user data
$curauth = get_userdata($author->ID);
// If user level is above 0 or login name is "admin", display profile
if($curauth->user_level > 0 || $curauth->user_login == 'admin') :

// Get link to author page
$user_link = get_author_posts_url($curauth->ID);
// Set default avatar (values = default, wavatar, identicon, monsterid)
$avatar = 'wavatar';
?>
	<div class="project">
    	<h3 class="project-title chunk"><a href="<?php echo $user_link; ?>" title="<?php echo $curauth->display_name; ?>"><?php echo $curauth->display_name; ?></a></h3>
        <h4 class="orange chunk"><?php echo $curauth->subtitle; ?></h4>
        <a href="<?php echo $user_link; ?>" title="<?php echo $curauth->display_name; ?>" target="_self"><?php echo  userphoto__get_userphoto($curauth->ID, 1, '', '', '', ''); ?></a>
	</div>

<?php endif; ?>
<?php endforeach; ?>

<div class="clear"></div></div><!-- end #ap-content -->

<div class="clear"></div></div><!--- INSIDE-PAGE -->
<div class="clear"></div></div><!-- CONTENT -->
<div class="clear"></div></div><!-- MAIN -->
<?php get_footer(); ?>
