Asp.net modification project

i have working project that was built on asp.net framework 3.5 , (i will like it to be on 3.5 not changed to 4.0 because of server issues) this project i will want to modify . This will require to 1) add Html Template: --- specifically for Home page-- then the rest will still be running on the old template: i will provide the template 2)Add Login on new home page:---default aspx 3)Create admin rights --- meaning that admin can use to create user login right to one or more different web pages.---- so it will mean that normal users do not have permission to view other pages except if they have permission . 4) User will have permission to perform a search on records and save if they want . this can be done by adding a search option On record page. 5) Admin will have access to search and trace a user activity . to know what user login in (Name Date Time and activity) this can be done using a search page. 6) Add A Save Button on Form “Save Form” This save button will allow user to save form in different format (doc, text, PDFs) and print .
