Website Design Cost Calculator

I want to have a website design build calculator with the same function as the calculator here: [login to view URL] It will be implemented on my current website and will need to match the design and layout i.e. colors and css of existing website. After the cost is calculated it will need to submit the data as a quote request to email address. I will need the ability to set the variables i.e. the cost associated with each element either xml or db admin or admin page your choice. Function must be similar to the one mentioned in link: [login to view URL]
