Have you tried clearing after the related posts?

<div style="clear: both;"></div>

<!-- Post ID <?php the_ID(); ?> -->

    <?php
        if(comments_open( get_the_ID() ))  {
            comments_template('', true);
        }
    ?>

That’s right. You can create the meta boxes for these post types so you can complete them while creating the post.

Plugins folder should definately be ‘plugins’.

They may have hardcoded a PHP contact form in a custom page template. You may be able to check this by going to the ‘Free Estimate’ page edit screen and checking what page template it uses.

If it’s something like ‘Contact Page’ or ‘Estimates’ or something other than default, there’s a chance there could be a php file in the theme root which may add the contact form after the content on the page is pulled in.

Hmm. OK. Check that AllowOverride is set to All:

AllowOverride All

Need a link to help fix.

Not to state the obvious, but have you enabled menu functionality in your functions.php file?

if (function_exists('add_theme_support')) {
    add_theme_support('menus');
}

OK. Hmm.

Not to state the obvious, but did you check permissions on your htaccess file? ie, does WordPress have the permission to alter the permalink structure in the htaccess?

Also, when you change to /%category%/%postname%/, does the htaccess look (similar) like this?

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

URL rewrites enabled for Apache? Like mod_rewrite?
