Custom JS or AJAX Calculator - $30-50 bids please

Please see attached spreadsheet. Looking to create a very small JS/AJAX/jQuery Calculator based on this spreadsheet. Red Cells are user input. White cells have formulas attached to them (pretty simple stuff). Should start with the demo data provided and allow user to input new numbers for the cells marked in red, with the remainder of the cells adjusting in realtime. Page should not reload as I would like to place the finished product in a modal window. Would like to add a button at the bottom - "Print These Results" - would take the calculator contents and format in a print friendly format and print. That's it - Let's get started! LVWebGuy
