I am looking for a perfessional to build up a website like this

http://www.readytofix.com/Inventory/List_2.htm

simple desing is ok.

I've upload the updated version of the proposal 
http://www.luxurymoney.info/car_new.pdf

for the backend, 
 1.the administrator must be able to add, modify, and delete the car model categories 
 2. the administrator must be able to add, modify, and delete the car in each categories 

the front-end proposal has updated as well. 
for the top-right brower, which is the car specification, there would be a main image at the middle. The size of the main image should be 720 height and 300 width and it must be able to auto adjust after upload 

Also, for the 5 small images, the display image must be in thumb nail. When the buyer click the thumb nail, there should be a pop-up that shows the full size image. Please use Lightbox http://www.huddletogether.com/projects/lightbox2/  

let me know if you have any other questions. 

How much time do you need to complete this job
