How to show Classified ads on the home page?

Hello. Below is the code on our home page that shows the latest posts in a particular category. How can I change this to show classified ads instead of the latest posts? Thank you.

<ul id="latest-posts" class="hide">

<div class="blog-thumbs-view">


$temp = $wp_query;

$wp_query= null;

$wp_query = new WP_Query();


while ($wp_query->have_posts()) : $wp_query->the_post();


<li class="blog-thumbs-view-entry">

<div class="blog-thumb">

"><?php the_post_thumbnail('my-thumbnail'); ?>


<div class="group-box-bottom">

<div class="blog-thumb-title">"><?php $thetitle = $post->post_title; $getlength = strlen($thetitle); $thelength = 57; echo mb_substr($thetitle, 0, $thelength, 'UTF-8'); if ($getlength > $thelength) echo "..."; ?></div>

<div class="group-box-details"><?php the_category() ?>

<?php the_date(' j F Y / G:i '); ?></div>


<?php endwhile; // end of loop
