Prestashop Module Needed

Hi,we need a fully working custom Prestashop module developed. The purpose of the module is to be able to create additional tab in product page for displaying additional info for products with full admin control in admin panel. The module needs to be developed in professional way,we would test it and payment would be released only after we finish thorough testing in our server. You would need to fix any bug that would be found. Escrow [login to view URL] would be needed for at least 3 months. You would need to sign NDA and we would prefer non Indians. thanks
