Need Suggestions For Online Store

Hy Friends i need suggestions for an online store.
1)I have a boutique and now i want to sell my items online. What i want is that user can also submit there designs and get there commission/persale. Is there any CMS that can help me for that except joomla, wordpress, Drupal
2)If this is not possible then i wanted to use Magento or Opencart which one is best.

I think opencart ,it has great features, including all the plugins required for an shopping cart.

You need to explain why you want to exclude WordPress and Drupal because only then we know what you don't want and can provide an objective answer.

Why? As a user of Drupal Commerce (and former Ubercart user), I am a big fan of Drupal platform.

For local ecommerce store, I use WordPress because the requirement is simpler. Both work like charm, not to mention that they're lighting fast because of the caching plugins available to the community.

And oh, because I can leverage the community, I really save a bunch on hiring people to fix code, etc. That is something else you want to consider...

Wordpress is always a good idea if you don't have a bunch of items, but if you do, I would rather go with opencart

Ok thanks a lot all of you
