BASIC Ticket Sale Website

I am in need of a very basic but contemporary looking website to sell tickets for an event that is coming up. The domain name has already been purchased. The website **initially** needs to be able to facilitate the purchase of tickets for a single event.? It also should allow me to add new events and allow customers to purchase tickets for those events also. I need full integration with google checkout as my payment gateway. I require you to build me a suitable back end user panel where i can add events/remove events / change price of tickets / type of tickets (senior/junior etc). The pages required are: HOME About Us Events Contact Us The website should send an automatic email ticket to the customer as soon as the payment has been authorised. I require design and implementation of the website including all testing by Tuesday April 23rd.
