Custom Coupon discount programming for website

I need someone to do the following: we are a cleaning service in New York. Each night around 20:00 hours, when we have last minute slots open for service the following day we would like to list these available slots, and insert our discounted price. (times and prices will vary by day so its important its SUPER easy for us to sign in and change this info and upload) Each special must go right to a booking form where users MUST enter data including credit card info securely, SSL then it will email that data to us and will provide a instant confirmation to the customer they have secured the slot. It will then remove the slot off the site IMMEDIATELY and in real time. CAN YOU DO THIS????
