Building a simple booking online form with payment

Here’s the brief (this needs to be up as fast as possible) Here’s the manual form page that this project needs to basically be the same as the following but moved into a automated booking calendar and online payment system [login to view URL] - Clients need to be able to choose from a calendar and only and pick one of three time slots on Saturday or Sunday (3 parties per time slot for now) - Choose from the optional additional children and food platters extras - Provide their contact details - See their calculation and total owing and then pay through a Paypal and/or credit card button - I have to have the bookings go directly into a calendar automatically (we have a Google calendar account if thats easy, so that all the staff can log in from wherever and see it, although happy to hear other suggestions). The bookings must be able to be viewed automatically with no human/staff input. - Client confirmation email when payment/booking is made and also staff email for notification to calendar entry being made Please let me know if you are interested, I will pay extra if the deadline is met! I need it by Monday 14 Dec.
