Adobe Air application that download historical prices from Yahoo finance or Google Finance for a list of ticker symbols

We want to get an Adobe Air application built that can download historical prices from Yahoo finance or Google Finance or Pfin for a list of companies that is stored in a CSV file. Each file should contain Date, Open, High, Low, Close, and Volume . Each company should be stored separately in it's own csv file. Attached is a sample Adobe Air program. We want to improve upon this by including the following: *The program will open a list of ticker symbols and download the Date, Open, High, Low, and Close for each symbol and automatically saves each ticker in their own file *Must operate similar to example DataDownloader application but with additional improvements noted below *Must be able to allow paste of ticker symbols and allow users to save that list *Must be able to open a list of ticker symbols; read each ticker and process the data. *Must be fast since this will be process thousands of ticker symbols *Ask user for input of start date and end date *Ask user whether they want to download using data from Google Finance or Yahoo Finance or Pfin *Ask user for input what folder the output files should be stored in *Ask user if they want existing files to be replaced or to just be updated (i.e. append from last date in that file) if destination folder already contains the same name of that file *The data should be stored from newest to oldest ***See attachment for sample air program along with sample data set.
