Create database query / download system for website using MySql.
Create MySql database (to be hosted on a server)
Create back office controls for uploading, sorting, deleting and editing data.
Create front end website code for querying and downloading database contents. An example of what we need is available here: <[url removed, login to view]>
Query and download functionality needed - query database and show number of results on the screen (data count) then allow customers who have enough credits in their account to download the selected data and subtract the appropriate number of credits from the customer's account.
Download must be saved (split) into multiple files and need to be zipped then placed on a download page for the customer to retrieve.
Website where this query / download page will be located is within a WordPress site structure.
