Website Customer Quotation Price Calculator

I require a "Quotation Price Calculator" for my website which sells LED Display Signs. The quotation is to allow customers to get a price for a product by selecting a product, and than select the variations associated with that product, and than have the quotation price emailed to them and to my email, rather than displaying the price on the screen, that way I am able to monitor the types of jobs customers are interested in. I want to use my current website to display the "Quotation Calculator", and have the calculator added into my site as a "HTML Snippet" if possible. If it is not possible to add the "Quotation Calculator" into my website as a "HTML Snippet", than we will make it as a standalone website. The "Quotation Price Calculator" is to have the following features - > Quotation Price to be emailed to customer and admin > Quotation Price or product variation prices are not to be displayed anywhere on the pages > Have a link within the Quotation form that is emailed to the customer, directing them to a page on my website to make payment I will provide the product and product variations information and pricing, including the formula for how the variations are to be calculated. There are approximately 5 x product ranges with approximately 10 x variation categories with an average of 8 x items per variation. We need this calculator made quickly upon being awarded this job.
