Enhance simple PHP/MYSQL scraper and email report script

We use a PHP scraper to track our sales at our distributors website. The current stock is stored in a MYSQL database, sales reports are sent by email. This job is to enhance the script with: *Login and admin interface *Hourly emails only if there were 1 or more sales *Daily report listing all products, daily sales count, and current count (even if no sales) *add/remove/edit product entries *add/remove/edit email addresses that receive sales report *A configuration page to setup product emails. For each email address we need to configure: which products to report, if they get daily or hourly reports. There should be a "all products" option so the central office does not need to update the permission each time a new product is added. For example: X and Y get "My widget" in their report, but only X gets gets the "New exciting product" numbers. The script and sample database dump is included. We already have daily/hourly reports setup, more code and data can be provided to help get you started.
