Convert Excel 2007 to PHP web application

I am looking for someone who can convert an Excel 2007 based price calculation database (no macros, only formulas) to a working application in our website. This can be PHP or any other language that suits this purpose. The database should be easy to maintain (for instance driven by csv upload of database) and the final application should render within a template on our website. Once someone has calculated the price, he should be able to print, email or submit the data as an enrolment. Some improvements still need to be made to the existing spreadsheet to prevent data error. The (almost finished) spreadsheet is attached. This is a first step that we're looking for as we ultiamtely want to link our online booking system to our Salesforce environment. Many more projects related to the development of our online booking system can follow for a skilled and professional expert.
