52808 stock market simulator

Im looking to create a web site of a U.S. stock market simulator, similar to the one at [login to view URL] where users can trade with pretend money in a pretend account. I want a site not like the whole investopedia web site, but just the market simulator. Users should be able to log in, and have access to their portfolio of stocks. Users should be able to buy new stocks or sell existing stocks at the current market price, based on actual market prices of the NYSE and Nasdaq, which can be taken from one of several sources. trades dont have to be real time, but should be within a reasonable amount of time. Users should also be able to buy limit orders or stop loss orders, and trade options as well. that is pretty much the extent of the entire site I wish to create. am open to ideas about how to create the site. if you can do this windows based that would be fine, but if not that is fine also. will be getting hosting service soon after learning how site will be created. thank you
