Schedule courses and pdf from list courses

Hi. Please, the site offers training courses. I have to make a form with the ability to choose the course course and the course date by showing the free and busy days on the calendar. After completing the form (compulsory the choice of the specific course in the proposed drop-down list), the user should receive the PDF linked to the chosen course: you would be nice to advise me how to manage the course agenda and the PDF to be linked to specific course, to be sent to the user?
