30869 Simple PHP Script Modification

We have a working store script that consists of a dynamic category menu and product display. It currently outputs top-level categories only and displays the corresponding products in html. We need the menu to include subcategories up to 2 additional levels and display those products as well, ie: Category1 - Subcat1 - Subcat2 -- Subcat3 -- Subcat3 Category2 - Subcat1 - Subcat2 Programmer will be given the current script and a mock database (sql statements or excel spreadsheet) and is expected to use own development server. Timing: We expect a quick turnaround on this (one day) so please bid only if you are available to begin work on this project immediately. This is the first of many script modifications and we are looking to build an ongoing relationship with a reliable programmer.
