Adjustment to my asp code

ok guys i recently learnt asp and cannot finish my project. I need to deliver this project in like 2 days. I have a reservation form for a villa that needs adjustment. It needs to limit the amount of ppl staying at the villa to 7. Also there are some funny rules with the rates. If 4 persons are staying the rate is $300 per person for up to 6 days and 285 per person for 7 days and above. If a 5th and sixth person stays they are charged 50$ per person no matter how long they stay and if a seventh person stays then that person staysthen that person pays 25$ no matter how long he stays. Lastly on my resevation calender i want a legend to show available and booked days colors. and of course integrate the form to paypal.
