Program PHP crawler that fetches category directories and stores structure in mySQL.

We need a small PHP script for a concept demonstration. The script will spider all the category and sub-category names, upto 4 levels deeplinked, and in 3 languages English + German + French of www.kompass.com. Only the categories - without the level where the firms appear. The category depths range from 2 to maximum 4 levels. This PHP script must store all the retrieved category names in their logical order into a mySQL database (the sub-categories must be referenced through a numbering system to their relevant top level categories). The result is 3 tables of complete category trees (separated by the 3 languages) in one mySQL database. Your work includes the programming and successful testing of the PHP script (PHP 3, 4 or 5 is not important) as well as the definition of the mySQL tables/fields that the script requires to store the category names. When completed and running, you send the PHP script together with the "create table" commands for the database. Willing to pay maximum $250.- as it's only for a demonstration.
