Credit Calculation for Joomla

Hi, We are a young team in Switzerland and make promotional appearances for different customer. Now I have a request to create a credit inquiry's website. For this project we would need a calculation including possible inquiry form. We want something like the following links: [login to view URL] or [login to view URL] Front the short input the coordinates (loan request, rates) - Following the proposal - I will then be forwarded to a form (credit selection, personal information, notification of the application). The bank then receives a mail survey / form by mail for processing. We need this to integrate into a Joomla Webpage. Thank you and best regards, Davide Spanio CEO
