Convert Excel Spreadsheet to PHP

I seek a PHP programmer to convert an Excel spreadsheet to a PHP 4 script. The Excel spreadsheet will be provided to the winner bidder. It already contains all the formula's to do the math. The PHP script must be stand-alone and not rely on Open Office or other spreadsheet code or components. Your role will be to build an interface that matches closely the look and feel of the existing spreadsheet. It does NOT need to be AJAX. A refresh button to update the figures is OK. The yellow boxes are input fields. All other fields are calculated. The system does not need a SQL backend. It is single user. The system can read a single-user flat file for initial values. The system should not use Javascript to calculate values. The system does not have to look exactly like the spreadsheet, similar is OK.
