Gentle Giant Studios is looking for a new eCommerce website. We want a site that is Joomla-driven and are fine with using an out-of-the-box shopping cart solution as long as it's functional and stable. 

We are looking to review portfolios that feature Joomla-based sites, specifically membership-driven and eCommerce ones as well as sites with original templates and layouts you have built yourself.
