Retailer Marketplace with Advanced Listings

I’m setting up a business-partner marketplace that caters exclusively to retailers and want it powered by Fluent Cart (or an equally seamless cart solution if you can justify the switch). The core of the build is straightforward: give retailers everything they need to sell and fulfil orders in one place, while I maintain central control of the platform.

Here’s what absolutely must be live and working:

• Product listing – but not just titles and prices. Each retailer needs the ability to add custom attributes, searchable filters, multiple images, and rich-media descriptions.
• Order management – a clean back-office for retailers to confirm, track, and update orders without touching the site’s code.
• Customer reviews – buyers must be able to rate and comment, and those reviews need moderation tools on my end.

I’m open to your preferred tech stack as long as it meshes smoothly with Fluent Cart’s checkout flow and supports future add-ons. Please outline your approach to:

1. Structuring the database for flexible attributes and filters.
2. Building (or extending) the retailer dashboard for listings, orders, and reviews.
3. Ensuring speed, security, and mobile responsiveness from day one.

Deliverables are the working site on my hosting, documented code, and a quick onboarding guide for new retailers. If this sounds like your lane, tell me how you’ll tackle the advanced listing logic and any plug-ins or frameworks you’d lean on.
