The task should be simple to understand. We require...
1) Our existing installation of osCommerce to be able to import a text file generated by a software (see attachment), that will self-populate and update the site catalog without having to use the admin panel to manually enter product changes or new information.
2) A button which will also generate a similar report on the site's catalog contents.
3) A method that would allow certain login/pass combinations to show different things to different people. For example if username 123 and pass 123 are entered, the price of items would be $5. If username 456 and pass 456 are used, the price now becomes $6. Etc.
4) All existing bugs (there aren't many) to be fixed.
NOTE: If all is done to our satisfaction and in a timely manner, we will gladly pay a bonus premium for the excellent work. We are exceptional employers, and would like to work with you in the long term if you're worthy. (We produce many projects requiring PHP designers)
Please do not expect payment for poorly done work, or incomplete work. All tasks must be completed as we have asked. Please have a strong grasp of English as well.
