Develop PHP based FV calculator for my website

I posted this previously as a Java or C++ project, sorry forth mistake, it should have been a PHP project. I currently have an excel spreadsheet that allows my subscribers to do what if analysis that shows FV. it is a simple spread sheet that uses FV formulas. I need to put this calculator in my website by march 23rd. i am attaching a copy of the excel file that shows the calculator that i am talking about. i must be interactive allowing my subscribers to enter values for certain variables to calculate FVs. please make sure you understand what i need before you place a bid. please feel free to contact me with any questions cheers, Dave
