Looking for a web developer to upgrade an existing website. Currently, when a customer places an order, the site sends a WhatsApp notification. I need to add: An email to the customer with an order summary (items, total price, shipping/pickup details). An email to me (the business owner) with a notification of the new order and all order details. I already have the full site files in a ZIP package. The solution should use proper HTML email templates and secure sending (SMTP or transactional service like SendGrid/Mailgun). Please include relevant experience, estimated delivery time, and warranty period. Budget: According to the packages below (Basic / Standard / Pro).
