I have got a website which is using WordPress and a PHP-based custom page which displays data from an SQL-DB. The custom page is written in PHP and shows a matrix table. I would like to enhance the website with another such custom page (also written in PHP) that displays the same information as the existing page - but in a slightly condensed form (some rows can be consolidated based on simple, predefined rules).
In addition to the aforementioned, there are some small changes (i.e. to optimize the display on mobile devices, rename existing columns) to be made on the existing custom page.
Detailed spec is available on request. Budget: 80 $
