Grok is a multipurpose, 100% responsive, simple, and clean cost estimate built with HTML5, CSS3, jQuery using Bootstrap4. With its PHP engine, Grok is able to generate a PDF summary about the order request which contains a PayPal link for checkout. The summary is sent in attachment by nicely formatted email notification. Although it is not a WordPress plugin, Grok can work within WordPress in a separate folder. Comes with premade color variations and layouts. It can behave as a standalone site or can be integrated into HTML or CMS systems.
