Stock Price Puller - PHP/PERL SCRIPT

hello, I need a PHP or Perl script which can pully STOCKS by price for instance if you go on [login to view URL] and on the right you will see a stock search text field you will simply put stock Symbol such as for Microsoft the stock symbol is MSFT and it will give you the market opening and stock price, I need a script which can pull all the stocks list wise along with there SYMBOL if you enter the stock market price for example. I will enter in a text field $2 after hitting search it must pull all the stock symbol based on $2 or some what close to $2 or If I wanted to pull stock based on $.5 i.e. 5 cents it will show me the listing of all stocks based on that price. I dont care from where you pull the data but the data must ber 100% Accurate. My Budget is $50 for this project please only bid if you can do this project. Thanks
