I need someone to build a single-step checkout module that integrates into the Contao CMS/Isotope eCommerce framework and follows its conventions for payment module integration, mootools for ajax/js, and condenses billing, payment and order processing into a single form post (after validation has passed on all fields)
BIG-Commerce contao theme. Actually i have made a custom calculator.

After all calculations there is a price and product details like height, width, materials etc. Now i want to add this product in direct shopping cart. Is there any technical support i have. Please respond asap
