Shopify Marketplace Build & Launch

I want to create a multi-vendor e-commerce marketplace using Shopify, similar to Ugaoo. The marketplace will allow multiple vendors to list their products, manage orders, and receive payouts.

Core Requirements:
• Shopify setup with premium theme customization
• Multi-vendor marketplace integration (Webkul / Shipturtle / similar)
• Vendor dashboards (product upload, order management, payouts)
• Payment gateway setup (UPI, Cards, Wallets, COD)
• Shipping/logistics integration (Shiprocket, Delhivery, etc.)
• GST invoice/tax setup for India
• Customer features: product reviews, coupons, wishlist, abandoned cart recovery
• Mobile-friendly, SEO-optimized, fast loading
