We have an ecommerce website [url removed, login to view] built in Prestashop. We need to do some bug fixing and CCAvenue payment gateway integration into our website for which we are looking for a company who has resources to do prestashop development. I have attached document that explains the existing bugs in website in detail. For the payment gateway integration, code is given by the payment gateway to add into webpage, you will just need to do some formatting and normal redirecting or exception handling. Please go through the document and let me know the estimated cost and time for the development.
