You can easily implement a load-more function on your post or other custom post type by installing the WordPress Infinite Scroll – Ajax Load More plugin.

After installing the plugin, go to “AJAX Load More” to set the appropriate settings for your site and to get the shortcode.
You can customize the template for the load more items on this file: /wp-content/uploads/alm_templates/default.php
just make sure you have a FTP access on the site.
