We build a website by Drupal that need a function for signing up for travel itineraries.
1. Manager can post new travel with maximum of applicants and signing up deadline.
2. A itinerary may with several date. We need separate maximum of applicants and deadline for every date.
3. IMPORTANT - We build site by Drupal, you have to develop a module for those functions.
4. Maybe we need payment system for those travel itineraries in the future.
