Recommended eCommerce Hosting
 

I have a client that's looking for a good shopping system for their site. I'm looking for a specialty hosting site, not some xcart/osc/mage

I would recommend http://www.tucktail.com/ .It provides the ecommerce solution .Through this you can create a online store easily..

E-commerce hosting offers you with well equipped built-in tools in order to get successful business. This hosting is specially designed for business sites. They offers greater bandwidth, storage and backups facility.

So you need a paid shopping cart like magento?
