Shopify Developer Needed for Professional Listing Marketplace (No Checkout, No Subscriptions)

I am building AudiologyXchange, a professional-only listing platform for used audiology equipment. This is not a typical e-commerce store and not a full marketplace with payouts, escrow, or commissions. Please read carefully before applying. What This Project Is Built on Shopify A listing-based marketplace I sell my own inventory Other businesses can list equipment after paying a one-time, time-based listing access fee No transaction handling between buyers and third-party sellers Sellers handle their own payments off-platform Buyers browse freely and contact sellers directly If you are thinking “multi-vendor checkout,” “seller payouts,” or “subscriptions,” this is not the right project. Core Requirements (Phase 1) You will be responsible for implementing: 1. Listing Access Logic (Most Important) Sellers pay a one-time fee for a defined listing window (example: 30 days) While access is active: Sellers can create and manage listings When access expires: Listings are hidden or disabled No recurring subscriptions No commissions This must be implemented using Shopify + existing apps, not custom app development. 2. Listings Each listing must support: Equipment category Manufacturer / model Condition Included accessories Calibration status (manual field + badge) Seller business info Contact method (no checkout button for third-party listings) 3. Buyer Experience Free browsing Professional (non-retail) presentation Clear “Contact Seller” flow Clear disclaimer that transactions occur directly between buyer and seller 4. Owner Inventory I can list my own inventory without paying listing fees My listings may later support Shopify checkout (optional, not required for launch) 5. Admin Controls Approve sellers manually Remove or edit listings Override listing access if needed Basic visibility into active sellers and listings What This Project Is NOT Do not propose or include: Multi-vendor checkout Seller payouts or commissions Escrow or dispute resolution Subscriptions Custom Shopify app development Mobile apps SEO campaigns or branding work If it’s not listed above as required, assume it is out of scope. Required Experience You should have: Strong Shopify experience (Liquid, metafields, access logic) Experience building gated access or role-based functionality Comfort using existing Shopify apps creatively The discipline to follow a tight scope and budget Bonus (not required): Experience with B2B or professional-only platforms Experience building marketplaces without checkout Budget & Timeline Budget: $2,000–$5,000 total Estimated effort: ~40–50 hours Fixed-price preferred with clear milestones How to Apply (Important) To be considered, your proposal must include: A short explanation of how you would implement time-based listing access in Shopify without handling transactions One example of a past project involving: Access control, gating, or non-standard Shopify logic Your estimated hours for Phase 1 Generic proposals will be rejected. Final Note This project requires clarity and restraint, not overengineering. If you enjoy clean, constrained builds and understand when not to add features, this will be a good fit.
