Sorry to post this in the blackhat seo section but I didn't really know where to post this in general. Anyways, I'm looking to build a new website and I'm looking for suggestions on a good platform to use. The website will be like http://www.dhgate.com. I want to get sellers who will come on and be able to build their own "store" within the website. I also want them to be able to sell in bulk etc. and have similar functionality any suggestions would be appreciated, thanks.
