Develop a cost calculator for Bitrix

There is a layout that, receiving dimensions, draws the product. It is necessary to develop functionality and connect this layout. All this data and settings should be moved to the Admin part. So that in the future they can be adjusted. The calculator consists of 6 steps, each item in the steps must be configured in the admin panel. The calculator calculates the cost and creates a picture - then all the properties and the screenshot fly to the cart - an order is created from the cart and sent to 1c. Priority is payment by invoice.
