Page with Sidebar on Right Side

I have been attempting to use a child theme to modify Spun.

I am trying to create a Page Template that will show the sidebar on the right side (about 70% primary content, 30% sidebar content). I would like this sidebar to only show up when this specific Page Template is being used.

I have created a Page Template that looks like this:

<?php
/**
 * Template Name: Store
 *
 *A modified file for a Store from Spun's Page Template
 *
 * @package Spun
 * @since Spun 1.0
 */

get_header(); ?>
		<div id="primary" class="content-area">
			<div id="content" class="site-content" role="main">

				<?php while ( have_posts() ) : the_post(); ?>

					<?php get_template_part( 'content', 'page' ); ?>

					<?php comments_template( '', true ); ?>

				<?php endwhile; // end of the loop. ?>

			</div><!-- #content .site-content -->
		</div><!-- #primary .content-area -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>

And used CSS (found here) to try to accomplish this goal:

.page #primary {
	float: left;
	width: 70%;
}
#secondary {
	clear: right;
	display: block;
	padding: 50px 0;
	float: right;
	width: 30%;
}
.sidebar-link {
	display: none;
}
.page .hentry {
	padding: 0px;
	width: 100%;
}
.widget-column {
	width: 100%;
}
.one.widget-column {
	float: none;
	margin: 0 0 0 40px;
}

So far, I have succeeded in turning all Pages into 70% width, with no visible sidebar and no other successes.

The page is here: http://nekothreesixty.com/wolf-bee-alchemy/

I would also settle for making a new sidebar and widgetizing it, as suggested here but I have not had good luck getting that to work either. Anyone figured this one out?

If it is helpful to note: I have also modified the content-home to display Pages instead of posts, created a custom Page Template that calls all posts in the category Blog, changed fonts & colors.
