I want to launch five separate e-shops for auto parts under one OpenCart installation using the built-in Multistore feature. Each shop will live on its own domain, share the same product catalog, and carry its own logo, colors, and language settings, yet everything must be managed from a single admin panel. Here is what I need from you: • Install or configure the latest stable OpenCart on my server and activate Multistore. • Apply a clean, modern responsive theme to all five storefronts, adjusting basic branding (logo, palette, favicon) per site. • Integrate a robust product-filter extension that lets shoppers drill down by car make, model, year, and engine type. Speed and accuracy matter; the filter must appear on category and search pages and update results without full page reloads. • Set up the main categories, attributes, and filter groups so the system is ready for bulk product import (I will supply the CSV later). • Make sure each domain correctly points to its store, SSL is active, and the admin area lists all five stores for easy switching. • Provide a short hand-off guide so I can add products, adjust stock, and edit the filter data. If you have suggestions for proven filter modules or premium modern themes that fit the automotive niche, let me know; I’m open to recommendations as long as the final look is sleek and performance is solid.
