Web development

We require three eye-catching pages. A front navigation page that looks personalised with a login and a bank of half a dozen buttons but only two need to be active to access the other required pages. The buttons should be graphical to indicate their purpose. One of these pages needs to incorporate a fully functional web-based calendar with the ability to set notifications and the other page needs a datagrid containing half a dozen fields to enable personal details to be input/retrieved. Also, we need the ability to upload/download any file between PC and Internet. Both pages will work from a SQL server backend. We already have the database so it would only be a matter of adapting it to the required fields for the calendar and grid. All the controls should be AJAX based to look smooth and professional.
