Add a new page to existing web application

We already got a web app with few pages like inventory,brands, parts. We are looking to job scheduling page in which the end user can schedule the timeline and cost estimation for the repair of the vehicle. It will have fields like Customer Name,customer ID, repair ID, Vehicle brand,type,date of consultancy, estimated cost, delivery date which can be entered by end user they should get updated in database as soon as end user enters them in front end. It should also end user to check the same record whenever he enters that job scheduling page and search for existing. So , the page should allow user to schedule new repairs and also see for old records, repair completed records, repair pending records.,status of repair. We also need report functionality which should allow user to print reports with customer name,customer ID,cost estimation and delivery date as soon as end user enters the data in above mentioned job scheduling page.
