We need a WordPress + WooCommerce website. Crucial Requirement: The site must be built as a full E-commerce store (with payment gateways and cart logic setup) but launched in "Catalog Mode" initially (Prices hidden for bulk items, "Add to Cart" disabled, replaced with "Request Quote"). Key Features Required: Platform: WordPress + Elementor Pro (Must be easy for us to edit later). Catalog Mode: Hide "Add to Cart" and replace with "Request a Quote" or "Get Today's Rate" (via WhatsApp). Product Calculator: Custom input fields for Length x Width x Thickness that auto-calculates Volume (CFT). Experience with "Measurement Price Calculator" plugin is preferred. Logistics Check: A Pincode checker on the product page (Local vs. Pan-India delivery logic). Booking System: A simple form to "Book a Yard Visit" (Live Inspection/Video Tour). Future-Proofing: Install and configure Razorpay/PhonePe payment gateways but keep them in "Test Mode" or inactive for now. Lead Gen: Sticky "WhatsApp Chat" button on mobile and desktop. Deliverables: Fully responsive, high-speed website (Mobile optimized). Video Tutorial (Mandatory): You must record a screen video showing me exactly how to: Add a new product (with photos & description). Switch the site from "Catalog Mode" to "Live Sales Mode" (Turn on Checkout). Manage the "Request a Quote" inquiries. To Apply: Please answer this question at the top of your proposal so I know you read this: Which plugin will you use to handle the CFT (Volume) calculation for timber, and why?
