Show list of authors with latest post NOT older than a month

I found two bits of code. One gets me posts NOT older than a month the other bit gets me a list of authors and their custom fields, names, etc.

Can someone please help me integrate the two. One runs in the wordpress loop with a custom query and the other is a foreach (all stuff I don’t know much of). How can I get the two to work together.

Thanks for any help.

<?php
        $display_admins = false;
        $order_by = 'display_name';
        $role = ''; // 'subscriber', 'contributor', 'editor', 'author' - leave blank for 'all'
        $hide_empty = false;

        if(!empty($display_admins)) {
            $blogusers = get_users('orderby='.$order_by.'&role='.$role);
        } else {
            $admins = get_users('role=administrator');
            $exclude = array();
            foreach($admins as $ad) {
                $exclude[] = $ad->ID;
            }
            $exclude = implode(',', $exclude);
            $blogusers = get_users('exclude='.$exclude.'&orderby='.$order_by.'&role='.$role);
        }
        $authors = array();
        foreach ($blogusers as $bloguser) {
            $user = get_userdata($bloguser->ID);
            if(!empty($hide_empty)) {
                $numposts = count_user_posts($user->ID);
                if($numposts < 1) continue;
            }
            $authors[] = (array) $user;
        }
<?php
            foreach($authors as $author) {
                $display_name = $author['data']->display_name;
                $main_profile = get_the_author_meta('mainProfile', $author['data']->ID);
                $hover_profile = get_the_author_meta('hoverProfile', $author['data']->ID);
                $author_profile_url = get_author_posts_url($author['ID']);
        ?>

            <div class="da-author">

                        <img src="<?php echo $hover_profile; ?>">
