Alibaba or aliexpress Clone Script?
 

I'm looking for a solution to build a site similar to alibaba (multi-country option is not a must, as this will be a local oriented site), and there are two or three scripts I've found so far, (just google alibaba clone and 90% of the links take you to the same script / same seller over a few dozen websites). However, demo websites look like crap, and script looks like something that requires MS Frontpage for editing, very outdated.

Is there an existing script but more up to date? using well-known frameworks, twitter bootstrap (or similar), jquery-ui etc?

In effect, I'm looking for a multi-vendor, multi-subdomain shopping cart system (where manager of each company would be able to edit their own mini-site on their subdomain), while site root shows a mixture of products and ads. Interface should be similar to fiverr, not like '99 yahoo. Any ideas?

one bump for US crowd :)
