Excel FORMS WORKBOOK /VBA Coding

We do have a complex workbook. consisting of 1 long sheets with questionnaire need to be answered.
- we request to create front FORM end of each Section of the first sheet as independent form
- create Function Sheet where the newly created FORMS for each section of the first sheet can be accessed as FORMS meaning we should have 4 buttons accessing 4 FORMS each FORM is one of the 4 sections of the first sheet
- save DATA entered on the 1st sheet as a BACKEND DATA of each respective Section keeping the rules created on cells etc... and access that backend 1st sheets via protected password
- Make the workbook faster by unlinking any sources.
- Create & Print & email a Report with ability to edit before generation to PDF. REPORT will consist of some generic information (fixed) we will provide and based on the FORMS Questions answered by users
-Generate Invoice & print & email an invoice ( we will provide a standard invoice format)
-Each workbook has a rate& rules sheet that based on specific criteria entered on the FORMS it chooses the specific rates and this sheet should be very very hidden not accessed through VBA only by unique password
