Write some Software

This is a small piece of a much larger job that I will hopefully be hiring you for, provided that you do good work on this one. I need a script to go to a given URL, download and parse some data on that page, and save it to an html page that I can view the data in an organized format. The resulting displayed html page will be password-protected, by your php script. The script will run every 20 minutes between a start time and end time. This start/end time will need to be configurable, as it could vary from day to day. The data that the end script saves to the html page will be organized by a timestamp (timestamps will be displayed in EST - Eastern Standard Time) for every instance that it runs (every 20 minutes). I will need to see the results of every run/scrape on one page. More detailed information will be given to the winning bidder.
