One guy i know Shojib has helped his cousin who returned a graduate from the USA to make a buy-sell-bid site. It recently started operating, and from what i see today, it looks gooood! I am trying to hook up my all so talented market campaigning, movie directing, musician friends with these guys so they get all the attention possible. Well, this is their site: http://www.sheradam.com.

OThers have also started and shutdown before in similar attempts:
