Similar Script to Build Your Car

We have a wordpress site and we need a script similar to what you can find here [login to view URL] but the only thing different that we want is that it should show the prices change on the right side of the screen and the price box should scroll along when you scroll the screen up or down. You dont need to make it in wordpress. We can load it up on a seperate subdomain and it could pop up in a new window but you need to add the logos and similar aspects from the website to make it look similar. The following are the steps that we want the customer to go through:- 1. Select the Country. 2. Select The Model 3. Choose the Options 4. Review the options and submit the options via the website just like the forms with their Name, Address, Email, etc. to our email address for formal quotation. There should be a backend where we could put in the options for each of the models and add/subtract the models. If you have read all this, please write boats with your bid for us to consider and ask us our original website name.
