Car Builder Flash Software

We would like to build a flash software to use it for customizing cars in our workshop. The software will be simillar to this one <[login to view URL]> You can see that this software is only for Mustang but what we want is to be able to put different cars in and also we want to be able to change parts and edit prices of course. In another words the software will be as same as the link provided but we will be able to put different cars and parts. Some thing extra that we want is to be able to change the window colour as well to represent different window tiniting colours. Please e-mail me for any un-clear point(s). I will be glad to clear them. Thank you
