Booking system for Tours & Airport Transfer

I would like to add the following features to an existing website: 1. Customer visits website and input date of tour or transfer (8% charge if bookings are made last minute) 2. Pricing should be based on adult/child and option (with lunch/without lunch, car seat, etc) 3. Price calculation (deposit amount & balance due on day of tour) 4. Customer is sent to Paypal payment gateway 5. After payment is made, customer receives an e-mail confirmation voucher with booking detail, meeting instructions, and balance amount if only a deposit is required. Features: 1. Admin tool 2. Reporting 3. Travel Agent rates 4. Automatic follow-up emails
