Corporate Website

I am looking for someone to design a simple car rental booking engine for our corporate customers. See [login to view URL] for how the general public [login to view URL] needs to have back end interface so we can go in and change and add prices, and also run reports into csv files. The ability in the back end needs to be so that diff customers can have diff rates and also be able to put in their own reference numbers. Reports would then run showing how much they booked and how long for. All car images and details would need to be input into there as well. time is of the essence but it is essential once the project is done that we can control everything in the back end. We would need interactive screens on the first page which we could control.
