How to get custom post type title, excerpt, thumbnail and permalink by post ID?

Hi there,
I have to generate several "loops" to get the title, excerpt, thumbnail and permalink of a custom post type 'charity' by post ID, because I need to target each ID with a special class (absolute-positioned map pointers).
Can you help me adjust my code so I can get it to work? What I have so far doesn't work:

<span id="chty_17">
						<?php // Charity ThirtySix  
                        $args = array('post_type'=> 'charity','post__in' => array(36));
                        $custom_query = get_posts($args);
                        foreach ($custom_query as $post) :
                        setup_postdata($post); ?>
                        <dt><?php the_title; ?></dt>
                        <dd>
                        <?php echo get_the_post_thumbnail(); ?>
                        <h2><?php the_title; ?></h2>
                        <p><?php the_excerpt; ?></p>
                        <p><a class="more" href="<?php echo get_post_permalink();?>">Find out more &raquo;</a></p></dd>
                        <?php endforeach;
                        wp_reset_postdata();?>
                	</span>

This code only displays the thumbnail and permalink correctly. I tried other options like the below, but the excerpt isn't included:

<?php $post_17 = get_post(17); // ABORIGINAL CHRISTIAN VOICE NETWORK ?>
                        <dt><?php echo $post_17->post_title; ?></dt>
                        <dd>
                        <?php echo get_the_post_thumbnail('17'); ?>
                        <h2><?php echo $post_17->post_title; ?></h2>
                        <p><?php echo $post_17->post_content; ?></p>
                        <p><a class="more" href="<?php echo get_post_permalink('17');?>">Find out more &raquo;</a></p></dd>

Please help! Thanks!!
